Replacing The Fuel Pump On My 1998 Chevy Silverado K1500

- I had to replace the fuel pump on my 1998 Chevy Silverado K1500. Dropping of the tank is an easy one-man job. Putting the tank back in, depending how full the tank is, might take more than one person. All in all, it was a successful install, the truck is much quieter and runs very well now.

My 99 made that sound since it was new from the fuel pump. 126k later, it finally failed. Loud pumps from the factory in some of these. Doesn't mean it's going bad just MHO.
The birds in the back going crazy 😂😂
Such a clean truck
I appreciate it! I like to keep my thinks a clean as I possibly can!
Nice truck! Thanks for your post. I've had to replace mine twice on 96 GMC Z-71. Not a fun job. Thanks again 👍
Not so hard to remove but had a hell of a time removing the high pressure fuel lines. Yours looks different but mine had no clearance for the removal tool. I used a small hack saw to cut the plastic nipples off. Afterwords, the tool worked although I had to use a large screw into the plastic nipple hole/stub to hold on to as I removed the hose fitting. I suggest not to use the crimps that were included with the new adaptor harness/plug. Solder and seal with marine grade adhesive shrink tube. I would hate to see the wire pull apart while reinstalling the tank or even corrode while driving!. Tank is relatively easy to remove but a bitch to reinstall. Pump out the fuel once the tank is on the ground. It was still difficult to reinstall with an empty tank. Lots of finagling. I needed to use two floor jacks to stabilize. If you are an angry person, don't do it. This is one of the most difficult auto jobs I have ever done. And I have done a lot. Takes patience. Get a friend to help if possible. Next time I will.
Well done video, surprised your channel isn't bigger than it is
Thank you! I appreciate the complement! Maybe one day it will be.
You got the sending unit out now how do you change the pump
Dude you need to look at some cars & trucks from the salt belt. Then talk about how rusty something is !
Haha oh I know those are pretty bad!
Can I cut a square of the bed floor right on top of the tank pump? I could cover it later with a piece of sheet metal
You can. There's all kinds of methods to getting this job done. I just chose to drop the tank because I did not have the tools laying around to lift the bed and I didn't want to cut a hole in the bed.
Nice truck
I appreciate it!
I MADE A DOOR ON MY BED,ILL TELL YOU WHAT THIS WILL BE MY 2ND PUMP AND THAT SUPER EASY TOOK ME 30MINS.
making the door would take more than 30 minutes
The fuel gauge on my 98 silverado just stays full, would I have to replace the fuel pump or just mess with the sensor. TIA
Id start small before tackling the fuel pump. You could mess with the sensor, the arm on the guage could have gone bad, the ground wire for the fuel tank, or you possibly might have a slightly clogged fuel filter. Those are all cost effective things to do before I would go replacing the pump.
The new plug is what I’m worried about I’m not good with wires, about to put one in my 98 2500 soon
Just take your time with each wire and make sure you splice the wires together good. It takes a little practice but it's not too difficult of a job.
Same problem here. 2500HD and I can’t figure out which wire on the square harness is hot, ground, and I believe two sending unit wires. I’m trying to test my pump to see if it is any good before dropping tank or removing bed. I’ve tested my relay and I’m getting power and my relay is switching/working. But I can’t tell if I have a bad wire, bad ground or a bad pump. Any help is appreciated. And great job on the video. Much appreciated.
My mount for the front strap was rusted out, would you happen to know where I can order a new one?

This one should be a direct replacement for a good price as well.
@@bossadamsgarage thank you this helped!
I agree. It was easy. Putting it back in smh...had to use the harbor freight trans jack to get it back up
Buddy, if that thing isn't empty, that reinstall is a struggle lol
I have same truck what size is the tank mine is leaking and I can't figure out what size tank I need
So my model came with a 34 gallon tank, however, for the 1998 year model, the 5.7L extended cabs came with both a 25 gallon and a 34 gallon. So, if your tank would or does bolt up like mine, then you need a 34 gallon.
@@bossadamsgarage has the same back strap and front strap that goes around the tank
So what brand was your brother's, was it ac delco? I was told does not matter what brand name it is, still going to be foreign country manufacturer , ....friend of mine that works at chevy dealership says even the ones they sell are NOT USA manufacturered.
I always try to use ACDelco parts on this truck but I have heard some good things about brands that are not well known and some bad things. It's one of those "to each is own" kind of deals.
Question do you need to unplug the battery before installing the fuel pump or it doesnt matter?
If there is an electronic involved I unplug the battery. When you change certain things out you don't have to disconnect the battery but I always do just to be safe and to keep the codes clear in case there is a problem that pops up after installation.
Thank you@@bossadamsgarage
Hey where did you get the pump ? Where you buy it ?
I went to my local AutoZone and picked it up. I would have ordered it online but I like being able to see parts as important as this in person before purchasing it.
I have done this total job in 2 hours really its much easier to drop the tank than mess with rusty nuts that will strip on taking the bed loose I dont get it why would someone want to lift the bed I just dont get it dropping the tank is super easy and I have cancer if I can do it anyone can .
Do it with a full tank
@@grovesiderabbitdrive it till it’s close to empty siphon the rest out, easy bro
I dropped the tank. Filthy inside and out. No wonder the that old pump started frying the relay. I think i messed up tho. The fuel level always reads zero now
Check your grounds!
About to get into the fuel pump on my 98… Can you normally hear it kick on with the door open? I can’t hear mine.
Yes, I could hear mine followed by a very loud and noticable whine. Sounds like yours could be on it's way out. I suggest checking out rock auto to get a good deal on the pump.
@@bossadamsgarage really appreciate the quick response. I get about 12 pounds of pressure in the lines when I test from that Schrader valve by the intake but I don’t hear anything and it won’t start anymore.. started a few times last weekend, but as soon i put it in drive it stalled out..fuel filter looked original so I change that and it didn’t make a difference. sound like a bad fuel pump?
That's interesting. If its getting fuel up to the fuel rail with steady pressure, it sounds like it could be something other than the pump. Really the only way to rule out the pump is by lifting the bed a little, removing the lines and getting someone to turn the truck to the start position to see if it starts spitting fuel. If it doesn't spit fuel when they turn the key, it could just be the pump. If it does spit fuel, well then you'll have to start diving into the truck a little more.
@@bossadamsgarage pulled apart the intake to replace the fuel pressure regulator and clean up and test the injectors, no change. Figured I’d give it one last look before taking it in, found a bad ground between the frame and the firewall by the control arm.Replaced it and pressure went right up to 55 , runs great.
Hell ya! That's awesome you found that ground. It's funny how little things like that cause major issues.
After I'm done my new fuel pump gas gauge don't work
Did you make sure to reattach all the grounds and make sure that the grounds have proper contact? If so, then it could be that the little motor in the cluster went bad.
New 4 flat electrical connector part #?

I would recommend getting it off rockauto. They've always got really good prices.
Maybe easy if your truck isn’t a complete rust bucket but I just used a 260 dollar dewalt and can’t get the bolts to break loose
Get some WD or PB Blaster on those bolts, couple coats, let it soak in, and they might break free for ya!
just did my 92 Chevy ...
Hopefully it went well!
I just take the bolts out of that side of the bed and use a little scissor jack and jack the bed up then pull the pump out. Doesn't take no longer than an hour to do.
From my experience, if you're going to go that route, you need to remove all 8 bolts first so that you don't run the risk of bending the bed or breaking the bolts on the other side.
Anyone ever have problems with fuel lines collapsing
Dropping tank? Lift the bed bro.
I have a video on bed removal as well!
