Valley fuel leak

[AJH]

Have a pretty big fuel leak in the valley on my LBZ. Its been leaking since before I got the truck and was so small I wasn't worried about a drop or two. It seems to have gotten worse or I am just tired of it so I need some pointers.

Truck starts fine if you let it prime a second or two longer than the wts light.
If not it starts then dies. Leaking down the ps of the bell housing. Already installed on the truck was a ybridge and egr delete so I'm hoping they busted a brittle rubber line. What are possible causes? If it was the "freeze plug" on the cp3 would the truck still run fine?

More then likely one of the rubber fuel lines is leaking. Especially since it loses prime...

I would start with replacing those and go from there.

X2 on rubber fuel lines leaking. Had it happen to me, actually the clown that installed the dual fuelers didn't feel it necessary to put a hose clamp on the return line fitting on the CP3

That's what I was thinking especially since it seems to have gotten worse. I tried to fix this once and pulled a rubber cracked line off and replaced but that one wasn't it.



Mike I'm not seeing a link.

Why are you bumping this?

Do you really expect someone to have this magical answer to your leak?

Your going to have to either dig into it and figure it out, or pay someone that knows what they are doing to figure it out.

Nobody is gonna be able to pinpoint your leak from there phone or keyboard.

Good luck.....

I bumped it in the hopes that the diagram that was missing from Mikes previous post would magically appear. Either by him seeing the mistake or by another helpful member having it.

Yes, I actually found this the first time I tried to fix the problem. Should have checked all of them.

Glad you found it, what number in the diagram is it.?

 

[AJH]

That was my first attempt that didn't fix the leak, it is #352.

Since it loses prime it's probably 348

Took an hour today and ripped into it, removed a bunch of shit I didn't need to. 348 top clamp. I'll throw the belt and cold side pipe back on tomorrow. Thanks for the help guys.:thumb: I'll throw the video up if anybody cares to see it.
