Title: Fuel pump for Onan 4.0 BFA
Post by: 78BraveGuy on February 24, 2018, 11:17 PM
The fuel pump quit working for my Onan 4.0 BFA-1R/16020A generator in my '78 Itasca.  It is a Walbro 12V WEP 12.  I have not had much luck trying to cross reference this pump to a suitable replacement model.  Will any low psi (~4-5 psi) pump work?  Does anyone know a direct replacement that will work on this model generator?


Thanks, Brian

And TJ's says 'made in the USA' on the pump body. Definitely a plus over offshore crap.

My Onan pump quit many years ago.  I mounted a high quality universal pump near the tank and a good filter in the generator compartment.  Ran the wires to the new pump.  Has worked flawlessly for over 20 years, much better than the OEM pump.
