Fuel Pump Leak?
Posted by Joe On 2023/8/2 22:36:45
Hey gang. I've been running my freshly rebuilt mechanical fuel pump. I've never had the car run on its mechanical pump until recently. Went out for errands and driving around, ran great. No vapor lock, no missing, spark plugs read normal - all good.
I was re-torquing my manifold nuts and noticed a little splatter mark on the inside of the fuel pump heat shield. Wondering what's going on here. It looks like it would have come from the rectangular opening on the side of the pump. Is this normal? There aren't any puddles or drips, and the line isn't wet. I do have an electric pump as well, but it was only run briefly before I learned I needed to install a bypass line. Or maybe it's an incidental finding. I recently de-greased (with a spray can) and cleaned all my grease fittings; maybe something from that? Just want to make sure the diaphragm isn't already failing or something... Thanks, all!
