Fuel leak

What possibilites are there for a leak on top of engine, filing up the valley. I know there a pump located there and fuel bowl. Whats a way I can definately pinpoint the leak. It drops around five drops only after driving for a while. Doesnt leak any on short trips, seems to after driving longer distances and really gets good and warmed up. Any help would be appreciated, thanks.

Re: Fuel leak

Good possibility. There are several rubber fuel lines in the valley as well as o-rings that can leak.

Need to dry out the valley as best you can, sprinkle baby powder or flower all around and see if you can trace the leak. Or just pull everything, replace all the hoses and o-rings.

Re: Fuel leak

Thanks for the advise, I just noticed there is a shop rag directly under the fuel bowl, prob to keep it from leaking long enough to sell, lol, Im guessing there is a hose coming from underneath the bowl? And if I removed the bowl would it be noticeable if there was a pinhole leak in the bowl itself? Would this be a huge project or is it pretty cut and dry?

Re: Fuel leak

Fuel bowls are known to corrode and leak. Could also be one of the three hoses between the pump and bowl. Also could be the fuel pump leaking. Replacing the fuel bowl is not hard at all. it is two 13mm bolts, two return lines off the fpr and three hoses. Oh and the ipr plug. It gives you a goo opportunity to check out the condition of the wiring harness that runs through the bottom of the fuel bowl for damage.
