Tip- save a fuel pump

[Max Hubrich]

Here is a tip I picked up on in a non- automotive magazine.

"Keep your gasoline fuel level above a quarter of a tank. Low fuel means the fuel pump is no longer submerged in gasoline, which causes it to run at higher temperatures and give out well before it should"

Nobody needs to go through this problem if it can be avoided so easily.


Makes sense to me -

Your thoughts?

Like my granny used to tell me..."Boy, it costs the same to keep the top half filled as it does the bottom half!"

and less likely to get condensation if the tank is full.

Ok...not being contrarian, but...
I don't get it.

My fuel pump has a fuel pickup in the tank. That pickup is has to be located below a quarter of a tank, else you'd be out of gas once you parked or stopped in traffic for very long.

Lobstah-

I never had to replace one in my Workhorse fuel tank.

Maybe someone who has, will chime in.

Here is a picture of a typical Chevrolet, in tank, electric fuel pump.

It appears to me that the pump is mounted into the top of the tank. The "business end" of the pump is close to the floor of the tank. It still makes sense to me to keep it running cool by submersion in the gasoline is a big plus for longevity.

Mabye Ford or other OEM's operate differently.

That is a known design fault especially on the Ford powered Motor Homes. We had a 1990 Southwind on a Deere Chassis that had an "optional" External Fuel Pump as well as a Huge fuel filter near the pump! The External Pumps still wear out but are sure a whole lot easier to replace than those Infernal-Internal Pumps!

Electric fuel pumps are cooled by the fuel running thru them, regardless of if they are submerged or not. I prefer to keep my motorhome near full when it's stored, when I'm using it (or any of my other vehicles) I'll run it to empty.
