When I got back from picking up a load of alfalfa today, I noticed a good amount of oil on and around my AC Dual fuel pump. The oil appears to have leaked out of the top left hole ( two holes at the top ). Does this indicate a failed or failing diaphram in the dual fuel pump?
It appears I did not loose that much oil , checking dipstick.
Is this common? The fuel pump was rebuilt 4,500 miles ago or roughly 4 years ago. Still runs like a champ!
See attached picture taken later after I found the leak.

OK, Draft tube cleaned. After 50 miles today the fuel pump is still weeping a little oil out of the hole. Not as bad as last time.
Rebuild the fuel pump?
