thats a very good link. I downloaded the pdf for future reference.

While I was getting my filter from AutoZone the guys there let me borrow a few fittings from their loan-a-tool kit, on the honor code that I’d bring it back. A three way splitter,(two ends being male barb fittings, & the other end a shrader valve), some rubber hose & a few compression fittings. Plan was to cut into my steel fuel line and make a place to attach the test contraption then simply compression fitting it back together.

Didn’t need to use them after installing the filter but it was nice to have and a kind gesture that I will return with my business to them.

I was questioning the new fuel pump also it being an “Airtex” from AutoZone.

However it turned out to be the new fuel filter/regulator that was installed. Brand name “Proto”
Installed a “Duralast” filter/regulator, turned the key pressure shot up to around 60psi. Turned the key off, pressure dropped a few lbs and held.

If I could of had the correct hardware/fittings to tap into the fuel line, I would of been able to find the problem a whole lot faster and with a lot less headache.

Lesson of the day? idk, test test test and when you cant test anymore start replacing shit…

lol
now with my fuel rail and throttle body out of the way I can get after that bad valve cover leak, maybe this was meant to be.

the connections are two different sizes, cannot be reversed. theyre quick connect style and i cannot find any hardware to hookup to it. To test or block off the return etc.
any ideas? or anywhere i could find the hardware?
autozone and oreillys have proven useless

I’m about to try a new fuel filter and see if that corrects the problem(New Filter installed was a Pronto). doubt it but maybe.
I’v also pulled the fuel rail to watch the fuel injectors for leaks. None found everything looks dry at the nozzle and the outlet at the fuel rail.

I’v checked every inch of fuel line for leaks, found none.

With key turned on I jumped the fuel pump relay to stay running during all “diagnostics”
Pump only goes up to ~10psi. With key in off position all fuel pressure is lost instantly back to 0psi
I installed an Airtex fuel pump new from autozone, could this possibly be bad? Could my filter/regulator be bad?

idk so many questions so few answers, im about to start searching for fuel leaks with a lighter…

2000 Chevy S10 2.2L MFI Flex Fuel 2wd

I have low fuel pressure and am unable to find out why.

With key on engine off I have about 10 psi
engine on I have about 18 psi

with key off fuel pressure is lost instantly back to 0 psi

New fuel filter.
No external leaks from fuel lines.
Replaced fuel pump same results.
Removed fuel rail to check out the injectors and am unable to see any leaking.
The fuel pressure regulator is apart of the fuel filter which is new.

So wtf?

any ideas or suggestions?
