Thread: Low Gas Tank Pressure? [Fixed!!!!!]

i have NO pressure in my tank, and i think its becuase my fuel injector o rings are garbage lol. i need to replace them, but they have yet ot cause me any problems, so i have yet to replace them. yet

Haha yeah if you don't care about fuel mileage then it's all good.

I doubt they are the injector rings though, seems like it is a little too far away from the gas tank you know?

well the thing is, when i turn the acc on and engine off and build fuel pressure, i can sort of push the injector to the side and watch the fuel pressure go down. i imagine there being no pressure in the system there wouldnt be any pressure in the tank? i donno lol

Hmm interesting. That could be it, guess you never know until you try to replace them

Finally Fixed!!!

hey guys i've been trying to solve a similar issue. i don't always get the fuel gush when i fill up.

i recently thought that maybe it was the check valve that was going to the charcoal canister (that isn't there). so i removed the valve and capped the two lines at the tank.

that didn't help so i tried a new gas cap and it worked like once or twice and then stopped, no more gush.

i today i was thinking that since i don't have any emissions equipment on my car could i just use a b12 sentra gas cap (vacuum only, no vent valve)?

well i decided to give it a try, and low and behold in the one block drive from pep boys home i had a gush when i undid the new cap.

i just wanted to know there was any reason to not want to leave it as such?

GOOD JOB! I missed this one when you got it fixed Vadim. Good thing you found the problem.

As I mentioned in the PM be careful, if the fuel tank gasses can't escape it technically becomes a huge gas bomb. But reading over your text maybe your gas caps were just bad before this?



Why thank you Coheed, but it looks like I have something else that's not holding the pressure (probably since I'm not running an older style Vapor canister and my current line is just capped off hehe.
