Would you care to explain the logic behind that statement?


I don't know if he is correct, but a lot of people would agree with
that. The pump is cooled by the gas in the tank and if it gets low the
pump could run hotter.

In saw more in-tank pumps go bad due to clogged up fuel filters, in part
because of rust caused by condensation from tanks always being run low. A
full tank keeps the condensation low. Ethanol adds to the problem by
mixing that rusty water in with the gasoline so the filter catches it and
gets clogged up, causing the pump to have to work harder to deliver the
gas.

BTW, I wrote this before clacking on your link, so, sorry for being
redundant! [g]
