Anyone have a Vulcan big line kit and experiencing the fittings from the FF to IP leaking. Not the addapters. Solution?

 

Well, what's actually leaking? the hose or the fittings?

 

The fitting is leaking where it threads into the addapter. I dont want to over tighten it and destroy the fitting before I here back from vulcan.

 

Just tighen it. We use AeroQuip fitting on all sort of things here at work. But you may disconnect it first, clean real well, and retighten.

 

I just got off the phone with vulcan,and "just tighten the **** out of it" was there suggestion. I see you have a similar addiction,Toys. 82 chevy LB 4x4,82 cadillac eldorado biarritz,98 bayliner capri,03 Z400,01 Raptor 660,87 LT500,83 250r,89 dutchman popup,95 Tigershark Montego and recently 71 FJ40. When will it end?

 

It Never Does!!!!!!!

 

my big line from the filter to the IP was leaking as well. I was sure it was at the fittings to the metric adapters. I tightened as much as possible but was still loosing fuel

I decided to remove the entire line and replace it with the stock line. While removing the metric adapters to the IP and filter housing, I discovered lots of slivers from the supplied orings.

 

I had one of the JIC fittings leak. Rare, I know, but I replaced the 14mm adapters, added a hose clamp to the push lock fitting, and everything trying to get it to stop. Finally just cut the hose off an inch, and replaced the 8AN to 1/2" barb fitting, and presto! Leak gone! Couldn't see any problem with the flare at all, but whatever the problem, it's gone now!

 

That is a good idea. It just seems, you spend $67 on a preassembled hose kit it shouldn't leak on both ends. I can't imagine it is affecting my fp,since I got a 1 to 1.5 psi increase right after install(leaking). But now out of no where my idle preasure is @ 6psi down from 7.5psi, never below 5 wot now it hits 2psi wot. I think the in-tank is going out.

 

Remember that the pump is checked for volume, not pressure. You just increased the volume capabilities by increasing the size of the line, so pressure is going to drop some. Yours sounds a bit excessive though.

 

the leak will cauz u to lose pressure...i had too tighten the **** out of mine to get them to stop leaking, just be careful not to round over the fittings.they come off easier then going on. some how for some reason, deisel fuel will find a place to leak from...use your finger, the smallest amount of diesel leaking around a fitting will show up on your finger tip.just try not to crack anything.
