Coming from a truck with a 34 gallon tank to a truck with 26 gallon tank sucks so im about to order a titan tank. Has anyone run a sump in the bottom of a titan tank or should I just stick with the stock pickup system? Im going to put an airdog on it basically for the better filtration because we buy bulk diesel on our farm so the fuel tends to be a little dirtier and I don't want to get into fuel problems on this new truck as I have heard nightmares.
