I attached the fuel pump in the engine bay as did spud69. His car has done about 6k to date with no problems. Some people mount them next to the fuel tank at the rear.

Im no expert on what can or cant be done but i wouldnt use the standard wiring and hybrid ignition module to control advance etc as its designed for the standard pierburg carb.

Megajolt was easy to install and i had no previous auto wiring experience whatsoever.
