Honestly - I think that Rich mis-typed that. He and I and his mechanic had an in person discussion as well as over the phone discussions about fuel storage and dirty tanks.
I think it was just a type-o.
I moved to my current location in 2011, and at that time did not even have diesel tanks, in 2015 when I bough the tractor, i bought two new 5 gallon plastic suitcases to keep fuel at home.
I keep them outside, and know that condensation can be an issue, so I use the Mr. Filter to try to reduce/catch any algae in the fuel.
More detail is that when Rich replaced my fuel sending unit - he told me they pulled and cleaned the tractor fuel tanks as part of the process.
That begin said - the injector pump failed, then replaced, and failed a 2nd time.
So on freshly cleaned tanks, I received the tractor with a new injector pump - ran it 3 hours at PTO with the fuel that Rich put int he tanks plus 2.5 gallons of fuel I had at the house, and the 2nd injector pump failed.
so for argument sake lets say the first pump failed from dirty fuel, the 2nd one.... HOW - the tractor had new fuel filter, fresh fuel, freshly cleaned tank from the fuel sending unit repair.... and only 3 hours of run time.
I sake a lot on integrity... as a Marine it is a way of life...
Besides...
I and too dumb to remember any lies I tell, way easier to just tell the truth...
