Fuel Leaking

blageo23 · 09-13-2007

If I have my hood open you can smell fuel. Also when you turn the car off the fuel pressure goes down to zero(sometimes taking a min but usually goes straight down). Is there a dye you can put in the fuel to find a leak(like what they have for coolant, oil and refrigerent)? I have AN lines from tank back to tank. and there is no leak that I can see.

Are you sure the car isn't a conquest? j/k. Why don't you put a white paper towel under each injector and each connection joint for the AN lines? That's a good way to narrow it down.

Hmm, thats a good Idea, Never thought of that. Ill give that a try.

SS lines have problems with fume leakage and not holding pressure after the car is off isn't a problem.

You can feel around for leaks too. I would check the ends of the fuel rail. Did you use new o-rings?

He has TIGed on Earls fittings on the stock rail.

I'd start around the injectors. Make sure the top o-ring isn't leaking. Like fatty said, paper towels work well. Otherwise, just take a flashlight and look for wetness on the injectors, and around your fittings. That is IF you actually do have a leak

I would use a lighter or a match around each fitting and see which fittings start a flash fire, just make sure to take out your Nawwzzzzzz tanks first though.
I would look at the welded fittings or injectors for leaks. The fuel rails are nasty dirty cast aluminum which is hard to weld to.

MA welded it for me and then It was powder coated. I dont see any leaks around where it was welded

Maybe check where the fuel filter is. I have alot of troubles keeping that from leaking on me.
