One of the major reasons some people hesitate on installing EFI is the pump in the tank is a daunting task even for the seasoned mechanic. We have a tried built many of these units for our own installs, but not for the kits. We will now offer to convert your sending unit to a Sending Unit/EFI fuel pump combo. Revolution Electronics (a Corvair guy) is providing the stud through bulkhead for power. You must supply the sending unit and pump/filter. We will only convert sending units that have/purchasing Brown EFI kits. Call us when your order your system and have the pump and sending unit (used or new) sent to us.
