What exactly are you talking about, Sorry if im misunderstanding but can you go more into detail.

It's right at the cover of the fuel pump. In the trunk, driver's side, underneath the spare tire and boards. I'm assuming you're looking for it to disconnect to relieve fuel pressure.

To make sure your fuel pressure isn't too high when first installing it, you should have the AFPR set at the lowest setting first. It should all be explained in the provided link.

ya thats where they said it would be but it was under the car right outside the fuel tank! WTF! the only other question i have is does the gauge have to be facing striaght up since it has liquid gel in my guage?

 

[rush2252]

No the gauge should read upside down as well as right side up. If your going through all of the trouble of setting the initial FP by the jumper wire method you dont have to. Install the AFPR and set it to its lowest setting. Start the car assuming it will run on the low pressure. Turn off all accessories and adjust the regulator accordingly. The methods your performing are for checking FP on a stock setup.

ya i just don't know which way to turn the adjuster thou to make it the lowest setting?

 

[snowborder714]

Just install it and adjust it once you get some fuel running through it. It won't hurt your car if it's installed unadjusted. Then just play with it until you get it set correctly.

 

[garrek11]

so it wont hurt the injectors if its running too high

 

[rush2252]

The injectors are a basic solenoid. The more pressure applied at the rail the more fuel is dumped when the injector opens or "pulses" adding pressure is a way of bumping up the amount of fuel or decreasing the flow for tuning purposes. With the car at curb idle it isnt going to hurt anything to have it too high or too low.

sweet thanks alot guys.

ok i have one leak and idk if i should wait for the teflon paste to dry since i didnt use teflon tape?

 

[98gsxtuner]

You should have let it dry and then installed it just for the simple reason of maybe having gunk running through your fuel system.

 

[garrek11]

ok so i ran into a problem that when i screw on the guage it doesnt screw in far enough so it doesnt leak. any ideas on how to test the pressure without a guage or how to get the right adjustment? Oh and i have it all hooked up so the car runs good tell i can get the right pressure. could there also be a problem since my car is having trouble starting up now?

 

[garrek11]

ok so i got the guage on it without any leaks. and i adjusted it (without the vacume line) to 27psi then when i put the vacume line back on it stays the same. is it supposed to? ### i was reading that when you are at 5 pounds of boost it should be at like high 40's?

 

[98gsxtuner]

Adjust it to 43.5 with the line off, and did you put teflon tape on the gauge threads????

 

[garrek11]

yes and i got anohter fitting so it fits a lot better. HOME DEPOT!

Base fuel pressure for a 1G is 37psi with the vacuum line disconnected. When you reattach the vacuum line the fuel pressure will drop 1psi for every 2inHg of vacuum (eg-if your idle vacuum is 20inHg then the fuel pressure will drop 10psi to 27). Of course, when you get into boost the regulator will raise fuel pressure relative to boost at a 1:1 ratio.

Did you confirm that you have vacuum through the line by feeling with your fingertip?

 

[garrek11]

no not yet but when i reved my engine to boost the psi went down

 

[snowborder714]

1G auto - 43.5psi
1G manual - 37.5psi

What fuel pressure regulator do you have? It should definitely rise 1:1 in relation to boost.



Please fill out your profile so we know what mods you have done.

 

[garrek11]

The only mods i have to my car is a 255 fuel pump, a vision works fuel pressure guage kit and a BOV.

 

[snowborder714]

Do you have a link to the fuel pressure regulator you bought? I'm not sure if I've ever heard of that brand.

I'd like to say that it should work, but I can't find any data on it. I contacted them about it through the item's page so I'll let you know.

I haven't heard anything about these, but typically eBay items are not the best, especially AFPR's. Aeromotive and FuelLab (and some others) are typically the recommended ones.
