I finally got my fuel pressure sending unit hooked up, and fuel is seeping out of the threads a little. Not bad at all, but I don't want that. I don't think I am supposed to use any type of sealant on the threads, what do you guys think? I don't wanna try tightening the fitting anymore for fear of breaking it.

If it is a pipe tread, go get some liquid teflon sealant. Otherwise no other fittings should have any sealant.

jvog

Ok cool, I thought I had read not to use sealant on them for whatever reason.

On a side note, what should max fuel pressure be...like ever...

You should not have to use sealant on an NPTF "dryseal" fitting--that said, there are a lot of things in the world you are not supposed to do.

A bit of the liquid/gel stuff won't hurt; do not use tape.

If it's not bottomed out or already "too tight" you may want to torque it up a bit more...

jvog

Yea I may try to torque them a wee bit more. I took it for a drive and there isn't any fuel dripping or anything so it might just not another quarter turn or something.

Also while driving my warning light came on because the gauge went over 80 psi, when i recalled my peak pressure, it pegged my gauge (maxes out at 100)...wtf

Shouldn't need sealant, whatever you do dont use teflon tape like cliffy said.

uberstang1

100psi lol.......I would assume somethings up with the regulator. Might be why its dripping fuel too

jvog

Well this is at the fuel rail, also I have a returnless system which doesn't have a regulator I don't think? I think it has something like it but its not called a regulator...maybe?
