Fuel leak on 96 7.3
 

Morning All, my 96 has a slight fuel leak, SOMEWHERE?!?! I just changed the oil, wiped everything down, 300 miles later there is a drip, and some wetness on the clutch slave cyl.
Are there any common areas to look at? I am looking at getting some of the ultra-violet dye and run it thru and see if I can find it. 5 min. idling in the garage had a small drip on the floor, and that was after driving 6 miles home up hill.
I hate leaks, and I can just barely smell this in the cab.
Thanks
Joe

Most likely fuel pump. But your just gonna have to get dirty. If it is coming down the back side of the engine I would be it's your fuel pump. Been there done that. Not a hard repair just time consuming. Search our forum and there are several who have done write ups on it. I even think I did one but I can't find it right now. And no you don't have to remove the turbo to change the fuel pump. Just patients and time. Make sure you have a good set of tools. I don't remember all the sizes and stuff but you'll need an universal, a way to lay across the top of your engine to work on it. Get comfortable you'll be there a bit. Let us know how it goes. I gotta get back to work.

Hey man sorry to hear about the leak. My dad and uncle both had leaks after the switch to ulsd go figure.:-banghead Both of those leaks ended up being the fuel pump but while i was in there i got orings for the fuel bowl from HERE and about a foot of 3/8" fuel injector hose with the blue inner sleeve from napa. To look for the fuel pump leak, from the front of the engine look to bottom left of the pump for fuel being spit out or clean engine and put a towel there.

Now that i think about it both of their filter restriction sensors leaked too and got replaced with a 1/8" npt pipe plug. Might check there also, facing engine, right side of fuel bowl on the fpr, its metal and plastic crimped together and thats where it was leaking.

Good luck man

Thanks Gents, I have crawled all over it looking, guess I can narrow it down and start looking closer at the fuel pump then.
Thanks

Well NAPA has one in stock for about $104, is there anything else I need to get before I start? I read up on the electric fuel pump conversions,,,, WOW some nice work on those, but I don't have the time or the $ right now for that.
Our Maint. shop has one of the over-creeper things for working on the Fords, so I will borrow it friday night!! That should help, and one of the "official" mechs is a friend of mine, and he said he might stop by for a beer and assistance if needed.

Do I need anything else?
 

Hey guys, do I need anything else before I tear into this friday?

You'll need an 1 1/4" wrench ,not a socket and ratchet, to get to the banjo nut on the back of the pump. Not everyone has a wrench that big in the set. Other than that regular tools will get it done. I would do those orings on the fuel bowl while in there but doubt you would get them by friday. There are 2 copper washers on that banjo nut, be sure their back on when you tighten it back up. Also I got our pumps from oreilly's and they were alot cheaper than our napa. Same carter pump and everything. Napa was $125. Oreillys was 100. Sounds like your napa is better than mine.http://images.ford-trucks.com/forums...s2/cussing.gif

Yep, I have an 1 1/4" wrench, I used to stack towers and do cellular/microwave installs, ya needed the big ones!
As far as NAPA, I work for a privately owned company, that employs quite a few people up here, and our maint shop buys our parts from NAPA, and we have a pretty large fleet to keep up, so they give us a discount. Plus, when I have so many trucks in my fleet I use them for all my stuff I need also.

Thanks kawa, that is kinda the plan, but I like having the fuel pump with me, if in fact that is the culprit! If not, NAPA is good about returns :) !

Another spot that will leak fuel after time is the hard fuel lines that go to the back of the heads in the fittings there is a rubber seal the one on the passenger side head is close to the down pipe the heat from the exhaust will make it fail over time.

If you end up changing your fuel pump I would also change these seals The part number from Ford is -F4TZ-9C387-A- they were like 2 bucks

Good Luck ..Happy Hunting

THANKS!! I will be calling Ford 1st thing in the a.m. and see if they got em!! These are the little things that are greatly appreciated from here!
Thanks ALL! The nice part is that we aren't hooking up the 5th wheel until next thurs, to roll down south on friday, so I have a couple evenings if'n need be.

Urgent, before Oreilly's/Kragen closes!!!
 

Ok, to the right of the fuel filter, is a sending unit,,,, what is it, that is my fuel leak!!!!!:-X04

Bet your talking about the fuel restriction sensor. It's the sensor sticking way out of the fuel pressure regulator. I could see it dripping just looking at it. I just put a 1/8" pipe plug in it because everyone says it's not necessary.
