Um guys, i got the regulator back together and the car was running fine and i didn't see any leaks.... but after driving and smelling fuel, i took a look and realized that there was fuel pouring out from the front flange of the regulator.. i am currently taking off the plenum to check it, but why would it be leaking if all the screws are tight? if i can't fix this then i am gonna be screwed an have to buy the holley unit...

If you somehow manage not to kill yourself, at least have someone kick you in the nuts until you're completely unable to have kids...

Oh the horror! Buying the right part and not blowing up your car! The amount of $$$ you've spent on this "mod"... time involved too (granted mine typically runs about $27/hr) and you'd think the correct part is an actual bargin

LMAO!

ok, correction. its coming from the base of the regulator block, where the front hose goes into it. its tight and still leaking some..

Better check the 'O' rings. Even an aftermarket regulator can do that, but for 200x the price.

ya thats what i thought the problem is, i just don't understand how it will all of a sudden start leaking so bad. UNLESS it was because it looks like the hose isn't going in perfectly straight. im gonna go pick up some O-rings tomorrow. know what size i need?

Guest

I doubt its the o-ring. More likely its the housing not against the bottom part of the regulator. The front clamp usually sticks up, in the way.

madmax, could u please explain some more. what do u mean by housing? are u talking about the cap?

thanks

The line that goes into the regulator, in the front, has a metal clamp thats held in by a couple torx head bolts IIRC. The metal clamp usually sits up higher than the surface on the regulator. When you put the cap back on, it can end up on top of this clamp, leaving a nice gap.

well im pretty sure the leak is coming from the line itself where it connects to the regulator body. at first i thought it was the cap, and so i took the cap off and retightened it, and it leaked just as bad. so i loosened the two front bolts that hold that clamp on, and tried to pry the hose so that it went in more straight, and retightened those two bolts and the leak is alot smaller now, it was enough to where i thought it was somewhat safe to get me home. (had a fire extinguisher in the back). i now remember having some problems when i was trying to get that hose it, it was hard to push in and i think it was becuase i didn't lube the o-ring. and so i am wondering maybe if i tore the o-ring or something. i will however double check tomorrow to make sure that the clamp isn't causing the cap not to come down far enough. thank you for ur suggestion..

Vader

You should prelube the 'O' rings with clean engine oil before assembly to prevent scuffing and tearing (the same as for injector 'O' rings). If you have a damaged 'O' ring, you'll need to replace it.

As far as the line clamp interference, if you assembled the regulator before installaing it, the issue shouldn't exist.

ya i lubed the other ones, but this was the only o-ring that stuck inside the regulator housing instead of the tubing and i was in a rush. pretty sure that is my problem then

thanks alot guys:hail:

Vader was right, the piece that was torn off was inside the regulator body, and i had to blow it out with a straw after taking the cap off..

oh ya, before i took the old o-ring out, i decided to goto autozone to pick up a new one. and i was just going to see if they had a large assortment that i could buy, so in the future i could have some. well they didn't, but they supposivly did have a kit for the fuel rail, to replace all those o-rings, so i though, hmm i guess that will work so i don't have to come back.. well. the old o-ring is on the left, they size of the one they gave me was on the right. needless to say i had a bigger leak with the new o-ring they gave me then i did with the old one!! so i had to go back up to autozone and match up the size with the old one. everything works now..

Darnit, I just got the hot dogs and marshmallows.

haha, well we could of almost used them, if i hadn't of fixed it i was thinking about calling u over here to help me out!

Vader

That's O.K., Z.

Hang on to those weenies. Anth is about to play with the fuel pump on his ride, and DuffMan is thinking about installing a slave pump on his Camaro. You'll get your chances before the preservative wears off in your Plumper....

I have a new box of blue tipped matches that has not been opened, I would have like to have tried them out.


Let me know and I will be there, if it looks like they are going to burn for some time I will bring ribs.
