Fuel rail and fpg

[Watazz]

Okay so I relocated my fuel pressure gauge to inline and put my shrader and cap back on the rail but I'm still leaking ah the shrader. However I'm not leaking at idle or startup it seems to only be with load. any ideas or suggestions are greatly appreciated

Its not tighten down all the way.

Really? I was pretty sure I tightened it enough. Although I didn't want to over do it

So I mostly fixed the problem. I was going to put a valve core for tires in place of the leaking one, but I found one for a/c systems that I thought might work better. The a/c core was $4 vs the $36 from the dealer. If any of you see a reason as to why I shouldn't use this core please let me know.

Da** straight! It still weeps a little, however I cannot get it to do it while it is idling. Before it was dripping fuel, now it just gets the slightest bit wet, but the valve is no longer filling up with gas. hopefully this was the reason my mpgs sucked so bad. What do you think about using the the a/c valve core steve?

If it fits then by all means, it shouldn't leak once tightened down. Mines been off since 01' so I don't know too much about them.

Never mind, it's also leaking where the schrader meets the rail. I'm going to need a new rail.

can't believe that little valve costs so much.if you run into something ilke that again just go by a tire store, they'll give you one for free.

Yea I know its rediculous, I saw the tire valves however I didnt know if it would be able to hold up against unleaded gas. The A/C valves were more similar to the stock one, and they were bigger around the bevel so they would probably seal better.

I think the AC valves would be a better choice than tire valves as far as material selection goes. My basis is that AC stuff usually uses HBNR (flourocarbon - usually I see them as green o-rings, though the color is just dye from my understanding) while I'm not sure what seals may be in a tire valve. Vitron is also used in fuel components (usually the red o-rings are vitron). I'm not sure what they use for fuel rail valves, but my bet would be that if it can withstand freon and ester, it should be better than something that can withstand compressed air (or pure nitrogen).

But the risk being a burned out automobile, I'd go for a valve that was made for being in a fuel rail, the sealing surfaces may be incompatable. If cost is an issue, perhaps autoparts stores may have an aftermarket part, or perhaps a junkyard part?

I suppose this is all pretty moot considering your present need to replace the whole rail.

Already paid 96rscamaro for the new rail. I just dread taking the thing off, I guess this is what I get for modding my car :rolleyes:
