leaking studebaker US6 fuel pump

Post by sixbysix » Thu Apr 20, 2017 11:00 pm

I have a fuel pump that is starting to leak from a small hole on the underside of the fuel pump body
I am guessing the diaphragm has gone although at this stage i can start and run the truck ok
can anyone give me a heads up on likely problem and where i can get a diaphragm if needed

The diaphragm has failed. Ross Prince will have them.
Don't run the engine until you have rectified the problem as you may be pumping fuel into the sump.

Once fuel pump diaphragm is fixed, drain the engine oil & start with fresh stuff.... very lucky catch!
