When I bought my truck it came with a auxiliary diesel mounted in the bed of the truck. It has a pump and electric fuel valve to transfer the fuel and is larger then my main fuel tank. My question is ...
As far as I am concerned the sun doesn't rise and set on transfer flow. RDS makes reliable tanks, fuel pumps are available at the auto parts store, and nitrile electrically operated shut off valves are available on line. So it can be done at a fraction of the transfer flow cost.
I sometimes wonder if transfer flow had Sauel do their web site. :h
