1996 7.3 OBS low fuel pressure fix
HTML-код
- Опубликовано: 12 сен 2024
- just showing how i did a fuel pressure regulator spring swap for those that need the help. if y'all got any questions just ask. the engine idle was a lot smoother and it seems to have more power, the startup seems to be the same. i havent driven the truck so i cant be sure if i got more power out of it.. will try and update when i can
Wondered why I wasn't getting any notice of your uploads. Fixed it 👍
Awesome man, I'm still shit at recording/editing but I just do it for my own amusement. If it helps someone or if they get amusement outta it I'm happy with that
i love that tire guage trick.lol that's some clever shit!
Thanks, works just fine most of the time. Sometimes the gauge craps out but it's pretty rare. 👍
I've got a 1993 7.3 F 350 with 175000 miles it's starting to have a few problems, leaks on the return system ,glow plug system,mileage per gallon is getting worse and the seat is wore out ,hopefully by spring time I'll get them all fixed , the money tree is picked clean and I don't see any buds starting to grow, glad you got your 7.3 running stay safe TANK
that spring i swapped out fixed bad fuel mileage, it helped mine anyways, idle is smoother and has more power. for 25$ it aint bad. mines @202k miles on it. you should also swap out the air intake filter for a new one. fuel pressure and dirty air cleaners kill the mileage on these 7.3s
Hey John good video! Hope you’re having a wonderful holiday season!
ive had some fun hahah
For others watching-you can also do the “BB” mod instead of purchasing the $25 spring. The “BB” mod is adding a BB to the end of the spring to make the spring “longer” - Ill be doing this to my 7.3 and make a video showing the steps. I think a better/newer spring is the best solution but Im still troubleshooting to see my low pressure issue.
I had done the bb mod it doesn't always work, with the bb mod I only had 30lbs pressure. It's better to buy the spring honestly, it doesn't cost much
Take your fuel hose apart and blow some air into the blue supply line. The pickup in the tank tends to get clogged up and restricts flow. I took all that crap off my truck and did the harpoon mod . I'd start there then get the spring changed out. Also there's a screen on your FPR you can clean as well that also restricts fuel flow
@@johndowe7003 Will do- i’m getting a fuel pressure test kit in the morning at Harbor freight for 15 bucks i’m going to test on idle and under load - definitely will blow the line out too - I’ve seen where those two pick up tubes get clogged in the tank and if that’s my issue I’m just going to delete them if I have to go in there-Ill let you know what I find
Any trouble in other areas from the spring swap? That's a lot of fuel pressure! Also, did you list get the spring for the 99-03 7.3? I cant find one specific to my 96
no troubles at all, it does give a puff a of smoke at startup but im pretty sure the glowplugs are going bad. there's the link to the exact one i used.

You have a link to were to buy the spring is it oem or is the spring bigger
www.amazon.com/EightySixd-1998-07-Powerstroke-Pressure-Spring/dp/B071J3CM1T/ref=mp_s_a_1_1?dchild=1&keywords=EightySixd+Industries&qid=1623977785&sr=8-1 there's the link to it, the spring is the same diameter as oem but it is longer. It' can be a pain in the ass to get the fpr cap back on but it will fit for sure cause I didn't have to modify anything for it to fit truck . Just make sure you put a towel or something to catch the old spring and triangular needle that comes out. It's super easy to lose it . Let me know how the install goes.👍👌
Maintenance manual says 40 psi is stock. Has this held up since you posted this?
Yes, it held up just fine. I drive the truck everyday. On the non waste gate 7.3s (95.5-1998?) They need 55-60psi at idle.90-100psi at WOT. Most guys shoot for 75psi at idle.
From what I've researched a higher fuel pressure will help with cooling the injectors and should make things run better.
Is that on stock injectors and stock tune? I'll have to check to see if my spring is broke. Stock tune does not rev that fast for me. I did the BB/washer mod almost 5 years ago and haven't checked it since.
stock everything, the only mods i did were the delete on the fuel pickup, tank selector delete. your spring is shot, i did the bb mod on mine before i swapped out the spring and it still didnt help. i was only getting about 30psi at idle with the bb mod. now im getting 90 or 100 psi at idle. my truck is a 96 super duty with a zf5 transmission
where do I get this spring?
Sweetness ❣️
Thanks for stopping by 👍
What spring and where did you buy? I also have a 1996
Eightysixd fuel pressure spring 1998/07 6.0/7.3

@@johndowe7003 any updates? Run better? Mine is bone stock right now, waking it up I am.
@@dwayneshephard2575 truck still running strong. I had some bad injectors , got news ones and swapped em out, installed a triple fuel filter setup, got a new steel fladbed, new sa200 welding machine is on the truck . Got a fuel leak somewhere on the motor either a fuel pump hose or fuel filter bowl leak haven't really looked. I still have to do an oil cooler reseal but I've been putting it off since it's a pain in the ass. These engines aren't really performance, unless you plan on spending 15k for like 400hp lol . What I would do is start with fuel filters , then air intake mod then injectors followed by a chip. Anything else is just a waste honestly
@@johndowe7003 cool man! I’m going smalls.. 1) S&B air intake , installed. 2) 4 inch exhaust with 3 in down tube.
3) Banks impeller soon
4) new fuel lines, tanks and sending units.
5) gonna take out the dumb spring inside the fuel bowl and turbo fooler for shits and giggles
Do you sound like Mickey mouse, why no narrative?
no i dont sound like mickey mouse ya big chungus, i just dont like talking to myself like a moron. id rather have people draw their own conclusions on the video rather than have to say what im doing. more of a watch n learn type deal. i usually write a summary of what im doin in the description and if folks got any questions i normally reply/answer people.
He says the F-Word if youd watch the whole video lol
Next vid. Try sign language!
What kind of tires are on the rear
nankang mudstar radial MT 235/85R16. theyre about 31in tall, theyre excellent in mud and dont make too much noise on the road , you can easily get 50k miles outta them
@@johndowe7003 I’m thinking about them on my dually do they touch and do you need spacers or no
@@tuckercole1531 no spacers needed, and they don't touch I love the way they fit on my truck. Wish I bought them a size taller tho since my truck is geared so low I run out of gear at 65mph . My truck has 4.56 gears though yours shouldn't be geared that low anyways
@@johndowe7003 yeah i got 4:10s but they look like nice tires so I might try them
@@tuckercole1531 yeah with 4.10s you'll be doin 71mph @2400 rpm
Awesome!!
Thanks bud , just hauled two cords of firewood today and the truck ran like a scalded dog
I think this is my problem with my 99
did you get it figured out?
@@johndowe7003 I brought it to my tractor repair shop he got it going with new filters I think he replaced sock in tank and cleaned tank. He said there is a screen in pump on frame rail. He didn't belive until he cut one in half. Are your fuel lines cracked rusted that it is not keeping pressure. Or sucking air?
DID NOT MAKE IT RUN ANY BETTER...IT RUNS LIKE SHIT ACTUALLY....
You speaking about your truck or mine?
