diesel or gas

[GregWeld]

Having owned and operated large diesel boats -- with 1000 gallon (not a typo - One thousand gallon) fuel tanks... everything he is saying about dirty fuel is absolutely the truth.

When you have that much diesel "stored" --- and it has water in it (all diesel does) --- you can get all manor of microbial growth... that will wreck havoc on the fuel system filters and anything else it touches. It's easier to deal with on boats where we can run large filters and be able to switch to a back up filter if necessary. These RACOR filters spin the fuel to try to separate the gunk - and they have clear glass so you can SEE your fuel. That would be impossible on a pick up... with rocks etc. In the boat they're well protected in the engine room.

There are businesses that do nothing but clean fuel tanks and filter your fuel etc.

So I can see a truck that isn't getting used much - or buys fuel from a depot that doesn't pump much - getting seriously contaminated. And that spells Ex$pen$ive repairs.
