If it is the old design they did not have the self diagnosing feature of the newer design units.....

Onan parts prices are pretty high and they are owned by Cummins....

I have seen a lot of bad fuel pumps on many different models. I don't doubt the fuel is killing some of them....

Yes Rich, thats the one I have, exactly as you described. I just installed a new fuel pump and a water fuel separator filter. Is there any legit reason to buy the $260 onan pump? There was a decal on the original onan pump that said you must replace with onan pump only. No explanation of why. I thought that maybe it was a flashproofing thing kind of like starters and altenators in the marine industry.
