In this video I will show you how to test a 12 volt low-pressure fuel pump off of my RV Generator, an Onan Marquis 5500. This pump model number is 149-2331-03. The generator is 21 years old, but only has 57.9 hours on the meter. I am doing a complete maintenance on it, but this video is just about the fuel pump test.

Can it pull a vacuum head (maybe like 2-3ft of gasoline ? Does it use a piston-solenoid type actuation? seems like it vibrates alot...I've seen a similiar video of a pump with a ton of vibes and output looked like rythmic spurts....so im hoping this type of pump can "pump-air" to self prime the fuel if installed on-top of a fuel tank.

can someone respond me , i did same thing with 12v 1.5a charger i destroyed for this test and i only hear short vibrations for a sec or two and then they stop. is 1.5 too small amperage for this test?

The amperage draw is probably written somewhere on the pump body. Test the pump with a 12v car or tractor battery. If it doesn’t pump, replace it. They’re not very expensive.

Should my Generac have constant power to the fuel pump, while it is running?

in my opinion, yes

Well, it's back on the generator, working great, so I think we're all good now.

I'm thinking to use such pump for water Is that okay?

@Buckwsr 4 жыл бұрын

This pump came from a gasoline-powered generator, so it is specifically designed to pump gas. I'm sure there are similar ones out there designed for water.....

Yep that works. A German did a test and ran it for 10 days straight with water to test it. 3.5m high to pump and 1.8m suction

These pumps will pump intermittently when they fail, so this test is inconclusive.

Thanks. I trust you. But happily, this pump is back on the RV generator and working perfectly.

Tested my pump with cooking oil first.

That's safer than gasoline, I would have to admit....

Pretty dangerous operation with an open container of fuel and a 12 v battery with alligator clips inches away. Longer wires 4 to 5 feet away from the fuel source would be a much safer option. Just saying.

In retrospect I guess you're right. Didn't occur to me at the time. In case you're wondering, the experiment went fine, and no animals or people were harmed!
