How to Replace a 1990's Corvette Fuel Filter and Fuel Pump 
Авто/Мото
They certainly have their strengths. They aren't infallible, but they certainly have merit.
You two are the BEST! I'm a newbie when it comes to Corvettes. I have had F-bodies where you have to drop the tank or cut a hatch to get to the fuel pump, and was under the impression that I was in for a long frustrating day, or an expensive trip to the GM dealer. I was so happy when I seen how to remove the fuel pump from a C4 Vette. I can't thank you enough for posting this vid, you have saved me time, money, and frustration. I am now confident that I can do this myself.
You're welcome- great to hear from you good sir.
You're welcome, and thanks for asking. It's called the Power Probe 3 and I put a link to the best place to get one in the description above for your convenience.
Great video and very informative. Just picked up a '91 Vette and trying to learn where everything is. Thanks again!
To put in my two cents (Brian's internet is down for a few more days), it did not cause any problems to have all of those on the same mechanism It came out very easily and the wiring was straight forward.
nice work. I really enjoy the presence of safety through the whole process.
Welcome- I love Vettes too.
Helpful, direct video to the point with out a lot of unnecessary jabber. Thank you very helpful
They are easy compared to many. Time is a fuel pump killer. Many Vette's stick around and are loved and kept out of the wrecking yard for decades. You're welcome.
Amen- and you're welcome!
Oh good! It's just been posted! :) Glad you enjoyed it!
GREAT!! Yeah, I couldn't figure out how to get around the crossing strap, but Thank You for showing how to do it, or rather that you actually 'have' to do it to get the filter out. But you got good confidence to get that accomplished. It's just me, so I hope to be able to get this accomplished.
amazing video thank you! i wouldn’t expect from the corvette so relatively easy access to the fuel pump! that’s amazing! :)
Great job guys! Enjoy your vids. Keep up the good work!
Cool video, Thanks for your help. Will be doing this this weekend to my 85.
Very Helpful, thank you and Spanky too.
Thanks Mike!
Happy thanksgiving to you and yours Brian!
Aloha
Good video. Clear and understandable. Thank you.
Brian I have a 91 Vette ..once I thought I may have had a bad fuel pump, so I disconnected the lines and turned the power on ... I then went to the tank and it was pouring out of the line I knew the pump was good ! ( yes I did that out side )
Thanks- and Helloooooo Ireland!
LOL! Actually I was afraid something bad would happen if I took it out of the driveway but then Brian made me and it was awesome. Kinda like being in a casket though.
Some systems don't have them- like on Chrysler vehicles such as the Town and Country Mini Vans. (which have been plagued with problems directly related to the in tank feedback or filter feedback design.) The idea is to have flow which enables variances in fuel consumption to be readily adapted to, It's like a spillway on a dam. No matter the variance in the volume of the inlet- the reservoir remains the same level, but in this case it's the pressure and available volume that remains.
Hi Rob! Thanks! Happy Thanksgiving to you!
Thats a fairly righteous looking beard you have going man, and your assistant is very easy on they eye :-) Happy Thanksgiving to you both and to your families and thanks for all the great videos, much love from Ireland.
You guys are great together :)
Thanks!
You're welcome!
The rubber grommet between the fuel pump and the
Assembly is called a Vibration Dampener.
Thanks! There is a big following for vettes.
Very well presented.
+Charlie G Thanks Charlie! And thanks for subscribing and clicking that thumbs up!
Ha ha Spanky, I should have known that makes you one of the guys. You two are great not only informative but hilarious too! Can't wait till your next video.
This video is a very helpful tool for those do-it-yourselfer's and can save you a ton of money. My advise to those beginner do-it-yourselfer's is........fire and gas..bad combination so be very careful. I wanted to say to this couple..Great Job!!
Thanks for the info Brian.
a huge help ! THANKS!!!
Thanks
Nice job on the Video and good to see Spanky too!
Have a good turkey Day.
Good video. Thanks for posting.
Grandfather clause' help. Knowing the codes and abiding by them helps too. You'll notice my house is no spring chicken it was built back in 1957 before there were zoning laws. Being a good neighbor helps a lot as well. When I bought my place it was dilapidated, rodent infested and an eyesore to the neighborhood. Since I've owned it- it's much, much nicer and a boon to the neighborhood. I bought the place because it enabled be to do this.
I need to clean out the fuel tank on my '84. I see the sender unit gauge wires disconnect, glad to see that. I was worried I'd have to pull it out alone. This looks simpler than first thought.
I wish I had a 'Vette instead of an Fbody for no other reason than the ease of changing a fuel pump. Thanks for your videos!
Thanks, haven't needed this info yet but I figured I better pre-knowledge my self ahead of time. Why did they have to put the filter there. I'm under all my vehicles for DIY, but I get get rather cloister phobic under the vette. Not a lot of jacking points for stands and jacks. Great service you two are doing😎😎😎
+Corvette Coupe Welcome buddy! They did it out of convention or tradition from the trucks.
Corvette Coupe
LT4
BEST SHOW ON RUclips!Followed your procedures-replaced filter but didn't help. Pump comes on but goes off right away. Cold start gets it going-but it stops. Strainer a little dirty. Not bad. Blockage after pre-cats-any ideas?
My hypothesis was wrong here. It was a bad pump with an intermittent failure pattern. Those intermittent issues are pretty tough to diagnose.
Thanks-- I spent thousands of dollars and hundreds of hours in ME school for that!
Hey nice job on the video and tech explanations. Do you have any videos about the dreaded optispark that came on my 92 Corvette LT1 engine?
I think you video is awesome, thanks you saved me a lot of $$$$$$$$
Hey Brian, great video. Are you in NY ? Would love to have you do some work to my corvette. You seem very honest and experienced which is what anyone would look for in a mechanic. Been to too many rip off artists. Hard to find an honest guy these days
That's an excellent tip.
Wicked tiny o rings on the filter,people,should have extra when changing the filter if they drop one. And the thing the pump sits on works ! Very noisy without that black rubber support donut. I had a 94 ' vette coupe,,but no garage,when it rained it wouldn't start to easy as the humidity got into the spark system in front of the water pump,what's it called ? Optics park ? Anyway,nice work as always. Happy gobble gobble day !
Thanks ....
Greetings from Middle East...
Great video my 92 base model..died on the offramp in Vegas last night right after I got some gas..any tips besides the excellent ones in this video?..I've read a few articles on stallings out which included ecm..
Reset..fuel filter relay..and etc etc?
Thank you again for the video!!
Im working on a 89 with the same problem. The rubber boot on the fuel pump melted inside the tank and was sucked up in side the line .I dont think it made it passed the fuel pump assembly. The fuel filter was clean. My question is what s the little round cup at the top of the assembly. It has a line connected to it also I cant blow into it. could that have clogged is it important
nice video i was wondering were that fuel filter is and know i know thanks.
At least you were able to get to the pump without dropping the tank.
Thanks a lot!
+mikeandsid2000 You're welcome Mike and Sid! Thanks for subscribing and clicking that thumbs up!
Thanks for the video, while test driving a 1992 vette I just bought last week it ran good for 8 miles and then started bucking and sputtering and then died. I can start if I pump the gas bottle but it just runs for a second and dies. I'm hoping it's either the filter or the pump
Great Video!The assembly is the same for my 88 35th Anniversary.. I'm having a problem disconnecting the clip that connects the fuel pump.Did you use a special tool to pull up the little grey clip and then pull it apart. (I'm heavy handed and do not want to break any hard plastic electrical connections inside the tank ( I hate those clips especially when they get old and brittle) Any recommendations? Thanks.. Also, thanks Spanky for asking the questions
Awesome thanks for the video. It seems really easy to do a fuel pump on 90's vettes but does it cause any problems having the pump/sending unit/ and filler in the same mechanism? Are vettes known for bad fuel pumps? Sorry for all the ?'s I'm just inquisative. Thanks
Thanks! Turkey Day was fantastic.. for me anyway!
Aw thank you!! :D
LOL I like flashing lights and strobes too especially after sniffing GAS FUMES!!!
Brian do you work on more than one Corvette regularly? I recall seeing one or two others, but it was probably the same car and I'm imagining things.
I love seeing oddball fixes like this...Not that a fuel filter is an odd thing to change, I mean that I'll probably only see a handful of these in my lifetime so it's pretty nice to know what to expect when the time comes.
She’s a keeper
that sucks that his internet is down. Thanks for the info.
Yay Ireland!! Thanks! ;)
Thank you for a great video and very informative 👍🏻 Amazing...! I have a 95 C4 with 95,000 miles and the engine makes a popping sound when the motor is in full Throttle... like it's not getting enough fuel... so I changed the original Fuel Filter and the Electric Fuel Pump and it still does it... the new electric fuel pump is a (Percision Fuel Pump Kit)....Any ideas?
Thanks for the info mike and spanky is sexy.. Good to see a lady working on a car .Your a lucky man mike and again thanks to both of you for the time save .
Check for corrosion on the positive side. It shouldn't fail due to a lock out or security issue. I've serviced many 2011 Nissans and didn't have that issue. That #@$n battery/fuse thing however has been a problem on almost every single one I've worked on.
I work on different ones.
That's why it is usually braided back. I can always pull up my hood as well. But if you send a leather pilot cap... I'll totally wear it!!!
I used to use a funnel and listen for the couple seconds when the pump energized ....or ride under the hood while while spraying carb cleaner to get in shop lol
Quick question: is it easier to just loosen the cross-strap by the fuel filter or do you need to loosen the cross-strap where it mounts on the right side there by the filter and also loosen the bolts where it criss-crosses with the other cross-strap? I guess it might be better said: if I loosen the bolts where it mounts by the filter will it drops enough to get your wrench and hand in there to get the old filter out?
Thanks!! :D
I wish my car could do that noise at the end.
Brian, do you recommend replacing original muffler with some "sport" muffler, that will make such sound. It doesn't have to "scream" and too loud, just as in your video, at the end.
Brian, I have this same issue on my 96 vette but only when the temperature is in the low 30's or below. When it is warmer everything works fine. Do you think that the fuel pump is faulty or is it other electrical issues?
jisslebissle did you ever fix this?
Brian, a friend has an early 90's beat-up GM truck 5.0/5.7 TBI and the 2 injectors aren't spraying, i can check the pulse with a test light? I noticed he has 4 previously cut, poorly connected wires running to the injectors, i was thinking of soldering the wires 1st for him then check the pulse? Connect the test light to battery ground and probe so it should come on and off? it has a new fuel pump, i say 5/5.7 as he had the 350 installed, just want to be sure before he replaces module
There's a vacuum cylinder coming in on the left side pump assembly looking at it before removing. That small canister has a round plastic tube and spring inside it. What is its purpose and what does it do? It's more to the top of my 90 vetted vacuum I'm thinking and will it affect the running part of the car?
Nice I can work on my 86 vette and refer here
I have, but it's been a while.
please help i am trying to do the same with my 95 but the hoses will not come off
Hello, I was hoping you can help. I have a 1992 lt1 vette . I put in a new fuel pump , new fuel filter , new fuel pressure regulator , new injectors . The fuel pressure is dropping under load . The car has hesitation , misfire , and stalling . I also replaced the optispark recently . .. Would a bad pulsator cause this ?
Thanks so much. I can handle it! You just saved me a lot of money! Thanks!
Need help asap!!! Just replaced the entire fuel sending unit on 1990 corvette along with the fuel pump but the car still takes about 8 seconds to start when cranking, any ideas??
I have an 85 Corvette that won't start. I put a noid light on all of the injectors and I don't get a reaction from the four injectors on the passenger side. The driver side injectors are working properly according to the noid light. Have you ever encountered this or know of any problem area on the Corvette that may cause this problem? Thank You.
With that big grin on her face, she might just put an enormous mechanics lien on that Vette LOL
The fuel pump is pumping a higher volume than the engine consumes. The rest of the fuel that the engine doesnt consume is sent back via the fuel regulator back through the return line to the tank
can you us a engine compression tester to check fuel pressure
where is the check valve located? my 89 is hard to start in the morning and ok rest of the day. fuel drains out (back into lines/tank) loses pressure as soon as it is shut down.
What kind of exhaust do you have? Sounds really good!!
+fulltilt6 Flowmaster
+briansmobile1 sounds really nice. I have magnaflows. They sound ok but not as good as yours.
Just wondering , if that hose is bad or has dislodged on the sending unit and going back into the tank, how can it build pressure at all ?
I steam clean them if they need it. I like to keep myself and my tools clean if I can. If I'm dirty and I get into someone else' car- it's then dirty.
hey brian,, if i remove the battery cables for example from a 2009 nissan almera or altima ,, to work on the alternator then after the job ,i put the battery cables on and the engine wont start.. i presume ecu descofiguration or antilock system IT IS POSSIBLE TO FIND THE INFO OR PROCEDURE HOW TO START THE ENGINE AGAIN (you know for exampl GM 10 minutes ON ,10 secnds OFF 3 times and the 4th the engine CRANKS)) IN ALLDATA ,IDENTIFIX, MITCHELL or just the dealers has that information?finger crossd
No, I got it. :) Oh how I miss CBs!
Easiest fuel pump change I've ever seen.. Sure beats having to take off the tank or removing back seats.
I want to know where you got that tester from I need one
Troy Lemley nn
Brian is it true on these newer cars, that, if you run out of gas in them, you have to put at least five gallons gas back in them before they will start, to keep from burning the fuel pump up? BIKERB
That was easy... To watch. Lol. Good diag.
I guess I don't understand what the return line does....
