Quick question guys,
1. in looking for the fuel pump on my new project ( a 73 2.0, with dell's) I cant find the fuel pump! I'm assuming it must have been re-located to under the tank, maybe adjacent to the MC? , any other places it could be hiding? After cleaning out the old gas, putting in fresh fuel, changing the plugs and wires, I thought I would give it a try...it spins freely, but no gas...and when I click over the ignition I cant hear the pump so it's either dead, or maybe a bad relay.... -Adam |

Bill,
Thanks- the stock location was passenger side, adjacent to the battery, is that right? |

assuming the pump is still wired through the stock wiring/relays, also check the fuse near the center of the relay plate in the engine compartment. a quick way to tell is if the heater blower fan doesn't work--no fan, no pump.
it's marked as 91 on the picture:  i've had this happen even when the fuse looked good--all it takes is a little corrosion on either end of the fuse, and you've got no pump/no gas. hope this helps! |

Good call,
The fuse looks suspect.... On the pump- sorry if this should be obvious, but was the origional location within the engine bay, down low by the fire wall, or underneath, by the side of the rear passenger tire? |

Not in the engine bay but underneath, close to the firewall, not the tire. Tucked away in the corner. You need to jack up the rear to see it or get to it ...

Close to where the heater hose enters the body.

weak link skills. go to the classic thread forum and find andy's write up on the jumper wire ground trick from the relay board. you will be able to use the proper circuitry to power your pump.
