Nope, didnt change the seals, the only thing that has been changed on that truck since new has been the lift pump. It crapped out a few times (typical 24 valve) so I put a carter pump back by the tank. That was a few years ago.
Two tanks? Warming it up?? Why bother? If its above 45ish degree's just dump it in the tank and run it straight. When it starts getting down to the high 30's we start putting in more road diesel vs canola. In the winter it gets pure road fuel.
Ive been to a number of bio sites and most of what they preach is pure propaganda... They love to talk of how bad running veggie oil and the like is on your engine. Yet I have yet to see any proof from their side. Have you?
