Car is gutted except for the driver's seat, looking for the type of fuel cell that I need that I can still use my oem mounted fuel pump. Possible? Looking for something that I don't have to fill up after every pass.

you're better off using a external pump on a fuel cell, use a 5 gal with a fuel level sensor attached to it and mount it where the spare tire sits in the trunk so you'll have best placement

bosch pump? What do you recommend?
