and im not sure where its comming from.....im not sure if its the prv? or its comming from my fuel filter housing? im just not sure.......is this my prv?

because if its is there is no fuel leaking around it but it looks like the leak is starting from the line comming out of it near the fuel filter but im not sure.
here are a few more pics, the fuel leak is concentrated around the fuel filter but i have replaced the o-ring on the cap and tightened the crap out of the cap......im stumped, any ideas?

 

if its at the prv part those are copper gaskets i believe and they mite have a burr and thats why its leaking you can only titen them so much till they dont work i believe

 

well i havent even touched the prv so should i try to tighten it? i just got finished sprayin some brake/parts cleaner around the area so i can run the truck and see if its leakin anywhere.....thanks for the reply!

 

i dont think its at the prv i think its farther down the line

 

Look at the line right above the banjo bolt weld down stream from the PRV, this is where mine leaked. That weld seemed to have a crack in it on mine.

 

its from the cap on my fuelfilter even though i tightened the crap out of it its still leaking i went and bought another fuel filter so i can double up on the o-ring on the cap and see if that fixes it

 

I don't know if that is a good idea. The cap should be snug, not wrenching it till you pop a vein. Maybe order one of those nice caps from Geno's.

 

If it turns out not to be the cap, I had # 4 injector line crack right where it enters the head. Mine failed totally and sprayed fuel all over the place. I have read and talked to some who had it just crack and leak a little.

DO NOT check high pressure lines for leaks with the engine running using your hands. Use a piece of card board. The pressures in those lines can injure or kill you.

 

well the double o-ring stopped the leak and i was lookin for one of those geno's caps but didnt find it on the website
