Fuel pump question
 

Hi All:
I have a 1951 flathead V8 in my 1948 Merc 114. There is gas seeping from the underside of the fuel pump. The gaskets themselves do not seem to be wet. I used a mirror to look at the underside of the pump body, it looks like there are two small holes opposite one another, gas is seeping from one of these holes. Would a bad diagram cause this? If so, is there a kit to replace it? The pump works fine,I don't want to replace if not necessary. Can't find a schematic on the web.
Thanks and Merry Christmas
Greg

Sounds like leaky diaphram

It's entirely possible that your diaphragm is torn. Worse than that, if it is torn or nicked, you are probably also pumping fuel into the valve/lifter cavity and into the oil supply. Do NOT run your engine any more until you sort this out. If the pump has been pumping fuel into the pan, at the least you need to change oil. Hopefully you've found this in an early stage where oil change will suffice.

CHARLIE NY has the good diaphragms that are not bothered by corn gas. DD
