M.F. 50A backhoe

Bill Thompson · Sep 28, 2017

Just got a M.F. 50A backhoe 1975 3260 hours Perkins diesel. Machine runs very good but has a few leaks I am trying to fix. The guy I got it from had
replaced the fuel tank. Looks like fuel is leaking out the top of the fuel pump around the top gasket is that a normal problem. Easy fix to just
replace the gasket? Does anyone have the fuel pump part #. Has a leak at the center of the rotary cylinder. That looks to be a big chalange. Might
just let that go. Thanks

The fuel leak from the lift pump happens when the pump gets old (could be the original lift pump). You can buy a rebuild kit, but most just replace the lift pump with a new one. The rotary cylinder used for the backhoe the parts are kind of hard to find, and are usually expensive. The 50A has the Perkins A4.203 engine, the backhoe should be a MF model 54.

The lift pump is part number 886100M91
