I have a 2002 Camaro/Firebird LS1 engine and I just noticed the small valve under a screw on cover on the driver's side rail (front end). What is this for? Would this be an appropriate place to put on a fuel pressure gauge? Anyone have an idea what the thread / size is for a fitting/adapter? Does the Shrader valve have to be removed as well? thanks...

The threads are a -4 fitting. You can hook up a guage ther if you want. Thats where the dealer hooks up.

Test equipt hookup. Leave it a alone. FYI: Napa has standard fuel rail fittings for $10.00 that will allow you to mate a #6 hose to the rail. It's a quick disconnect setup.

Do you happen to know what the part number is for the NAPA fittings?

My local parts guy looks at me cross-eyed if I can't give him a year, make, model, and common part to look up...

Thanks,

No I don't. NAPA has a little rack of standard fuel rail and heater hose fittings. It's on there and it's around $9.95. You don't have to ask them to get it from behind the counter.

I looked in NAPA and even asked the guys and they haven't a clue what I am talking about. So I went to OReilly's and there they were hanging on the self..Ford, Chrysler...but no GM and they couldn't find it in their books.

The only source I have found is S&P version for $40 bucks. I have a plastic version that has a barbed end for a hose that I got from SpearTech, is this the only one out there?

be careful messing with that. i had one come unscrewed on me while i was driving. ended up pouring 1/4 of gas out onto my engine bay before i realized what it was (windows up, and i had just filled up and gotten gasoline on my hands thanks to a ghetto pump)

Messing with what? What unscrewed? Can you clarify?

russel makes a fitting and you can use a swagelock. i think the part numbers are posted in the FAQ sticky.

ok, i was talking about the small valve under a screw on the driver's side rail

sorry, i shouldn't be typing that late at night...

anyways, when i pulled over, the cap was gone and only a part of the valve was still in the rail. i have no idea how it came undone, but it stucked.

Well I can either purchase the connector from S&P for $40 or just take my fuel rail off and have an AN fitting brazed on it.

I am kind of tired of thinking about it and will just get the fuel rail modified.

Of course my time and gas money is worth something, and it might be a wash to just have the UPS man bring the connector.

As you can see I am still on the fence. Of course I still need a fitting for that water temp prob into the head. I don't want to drill and tap the head.

I used a 3/8 to -6 Russell hard tube adapter. No problems in a year and a half of driving.

Did the same with no probs.....

my friend on here NyToy removed the Shrader valve and used 3 to 5 couplings to attach his digital fuel pressure gage sending unit, it loosk funny sticking off the fuel rail a good 3 inches but it does the job without any mods, you can easily replace the valve if you removed the sending unit. to keep the fittings from leaking he used a gas-safe sealant and really had to crank the fittings quite hard, kinda scary since they are all so small, but now he has a fuel pressure gaube in the dash.

to remove the valve just take a small diameter rod and cut a slot in the end to unscrew the valve from the fuel rail.

good luck man.

or goto walmart/tirestore/bicycle store, and you'll find a removal tool near the valve stems.

I used the S&P adaptor,a guage adaptor and FP guage from Summit
