Re: MDJF Onan 15 kw
Use an electric fuel pump and bypass that mechanical one.

Re: MDJF Onan 15 kw
Sorry to say the pump is gone. But honestly the reason I had it was because I converted to electric and never looked back. It’s an easy swap. Unbolt the mechanical pump and use a block off plate from a small block Chevy. $15 at auto parts store. Electric diesel fuel pump was $59 I think. Ground to engine block. Positive to single lug on fuel solenoid. Done.

Re: MDJF Onan 15 kw
This is the pump I used. Not a high pressure pump at all, but I believe it only needs to maintain supply to the injection pump and then that takes over. If I'm mistaken I'm sorry, but I can tell you this exact pump worked great on my MDJF and Jeg's is selling it for half of what I paid. At $28, it's not much of a gamble.
