Fuel Pumps and Fittings MEP-803a

That's the front of the set. The rear is always where the control panel is.

It would appear that someone could not get right pump, or wasn't paying attention to what they were doing. Or, it was time to close the work order on the set, and " it's close enough for government work" crossed someone's mind.

Guyfang I took some photos from the FRONT of the unit showing the auxiliary pump plus one of the primary pump. If they put the wrong auxiliary pump in they sure did a professional looking job

Indeed, looks good. But there is supposed to be two different pumps. Would I change it? No, it works. Rule 3. If it works, don't screw with it. Or, maybe it's some mod that has come out, and we have never seen it before? Has anyone else seen this?

None of the 80x generators I have/had came with inline fuel filters. Not a bad idea, but nothing I have seen with ones I have crossed

I haven't had a need to use the auxiliary pump. I think I will fill the tank with it periodically from a 5 gallon can so I know it works and I can use it as the primary pump replacement if I get a pump failure since they seem to be hard to source.

I have a '99 Fermount 802a, reset 10/12 with 10.2 hrs. Indeed it has two E1074 pumps with filters. I have the same little filters on my 2007 831a as well. Pumping out of a drum you sould better have some sort of filter before the pump.

Thanks. I fill my 5 gal cans from my farm tank. It has a Goldenrod filter on it.

Howdy,

The small barrel filter. NSN 2910-01-553-6571 FILTER ELEMENT,FLUID (small barrel filter only) PART# 00-24000


It is attached to the fuel pump.

If you go to this thread and read the reset manual, it tells you all about the fuel pump

Also known as Airtex G-17. Fuel filter - 300 micron

Called AirTex technical support. The E11010 is 12V, but they do have two 24V pumps:

E8131 10-14 psi
E8135 5.5-9 psi

Both are in the 14 gph free-flow volume range. AirTex sells on Amazon.

Since:

1. My MEP-803a still has Facet fuel pumps.
2. It has a probable fuel pump problem.
3. The "official" replacements are hard to find.

I'm going to try an AirTex E8131 for the transfer pump, and E8135 for the auxiliary pump. Plan to install AirTex inline filters ahead of both and will check pressure on the 1/4" ID fuel lines before and after. Will report how it all turns out.

Any updates on how this project turned out?

Mine has been working fine with the smaller aux pump running as the primary. I just needed the right fittings.
