I recently replaced mine and supposedly you do not have to remove the base with the five lines going to it... just the pump with the three screws. Did that and when turned on had fuel going everywhere. Had to put the pump back on the new base and change the entire unit. If you have 3/8 bolts holding the electric pump on the base and the new one has 12 point screws you will have to change the entire unit as the opening for the pump on the base are not the same (too big). Before tightening the base to the motor, get all five lines to start as I could not get one line to start without moving the base. Some of the lines you cannot see what you are doing so good luck. I paid $312 for it in MT and no sales tax.
