Default gennie quit

The gennie has been fine forever, but tonight it was running for an hour or so and suddenly it started faltering, and then just shut off. I restarted it, and it ran fine. ?? Fuel pump? Filter? Tomorrow is another day. Lucky I have the Honda backup

Anyone know of a good replacement electric fuel pump/ part number/etc

Gardner, Mine did that and I tracked it down to the electric fuel pump ahead of the Racor. The electric pump mounted to the engine wasn't enough by itself under load.

Got to say the load was minimal. Second hour of just charging the bats, no AC or anything (hot water heater maybe). But I will look for the first pump, but don;t have stuff to get under there safely at this CG.Do you have specs or P/N for replacement?

On my 86 you can get to the fuel pump by running out the generator drawer. There's an electric pump on the Myanmar and a facet pump before the favor. Both electric pumps on my generator have quit at separate times so I mounted an electric Edelbrock pump made for diesel applications and it's working fine. It took a couple of fittings, a little hose, and a small piece of angle to mount it on.

It's a Facet 40109.

Similar thing happened to me a few years back ,Gardner. I replaced the fuel pump and that seemed to solve it, later on my journey the problem returned, it was the fuel delivery and return lines, they had gotten soft and dropped causing them to get pinched when I opened and closed the generator drawer. Good for thought.

Kevin,
Where did you mount the Edelbrock pump, before or after the Racor?
Tanks for the info Crit and Chap.

Raining like heck today, hope the gennie holds on till it clears

I mounted the pump after the racor by the Yanmar pump. It's easy to tie in there. When the Yanmar pump first went out I wired the facet, which I believe is just a priming pump, to run with the motor. I found the racor didn't like being pressured and would seep fuel. Since installing the new pump I've not had that issue.

Fired it up an hour ago and still running fine. When the weather clears up I will start checking things. Once before, over a year ago, it quit on a hot hot day with ac's running, It faltered and kept sputtering and surging and finally quit, It would not run right when re-started. after cooling off it was fine. I replaced the overtemp sensor and it has been fine ever since, until now. Except for the 12 volt fan failure last fall.

I have the three wire solenoid and I don't like the condition of the insulation where it enters the body. It seems dried and fragile. Lucky bought a spare last time it krumped I got a bunch of stuff just in case. But not a fuel pump.

I will try a full load test after the batteries are charged to see how it behaves,
(two AC's, couple of heaters, etc)
