Have the dealership put the new in-tank pump in the tank but at the same time put on the tank vent kit for quicker fill ups, vent the tank to avoid getting dirt in the tank and add a second pick-up line for a future aftermarket pump. Then you are six ways to friday ahead of the game....ya gotta keep thinking to stay ahead. My stock lift pump is still working and still on the truck and is able to be easily replumbed should my FASS give out. ks
