How long on average did your Cummins Onan vehicle mounted generator last in years?

This is an EXTREMELY common syndrome with older Onan's. Happened twice to me. The fix is trivial: There is a little rubber hose sticking down out the bottom of the genset. That is where the nests form (bugs are apparently attracted by fuel odor). Just poke around with a bit of wire to dislodge the mud. Instant fix.

Newer gensets come with a screen at the end of the vent hose that prevents the bugs from getting in. You can make your own easily enough.

Mine is 10 years old, has 140+ hours on it. I change old every years also I run sea foam every 4-5 tanks of gas. Sea foam good for both vehicle and genny , starts right up no problem.

It sure sounds like they've simply jerked you around long enough to rack up enough expense to sell you a new unit.

I am curious -- How much does it cost to replace the Onan?
