Where is the weep hole???

Hey folks,

I've got a pretty good fuel leak that is dripping down from the rear of the engine. I believe its come from somewhere in valley, but I can't see it. As a note too, I have a California truck that has the Bosch disk.

I was hoping to see the weep hole on the fuel pump to see if it's coming from the pump or not. But I can't find it. Can someone show me a pic of the pump and the weep hole?

Also, I originally thought I saw fuel dripping from the edge of the Bosch disk. Do they have a seam or anything that leaks?

I hate to sound dumb, but the reading I've done on the forum also talks a lot about a banjo bolt. I don't know what that is or looks like either, so if someone could show me a pic of one I'd appreciate it.

Thank you!

The weep would be hard to see without taking the crap off the engine. Soak the valley in degreaser, hit it with a powerful stream of water. Crank her up to dry and watch for the leak.

if the three hoses coming off of the fuel pump to filter housing are original, they are probably leaking. check there also.

Here are some pictures for you. I dont have a CA truck, but this should help you out.

You can see the banjo bolt there. Its a MF'r to get in and out if you have big hands, but its possible!

The blue hose is one of the hoses Sgt Dave is talking about, they crack and will leak. Replace the pump and hoses if you have a leak in the valley. 9 times out of ten, its one of those two things.

Id change them anyway, including the lift pump, and then inspect the fuel bowl for leaks or cracks etc. while its out.

I wouldn't waste your time trying to see the weep hole. Just start looking around for a pump (somewhere between 100-200 bucks), and get yourself 3/8", 5/16", and 1/4" fuel line. You'll also need a 1 1/4" box end wrench. (Your local Napa should have everything, though Napa's price on the pumps is up there)

Yep, that's a cali truck alright. But, one thing to keep in mind. I have a Cali truck, and I don't have that goofy black disc thingie. I think the black disc thingie is on '96-'98 trucks. (mine's a '95)
