I am going to be initially running a newly rebuilt engine on carbs instead of the L-jet and need to get the fuel pump set up for that.
Can I use the stock wiring for the pump? I think I need to have a work around since the AFM won't be installed. Can anyone shed some light on a good way to accomplish this. |

+1, thanks to Andy. make sure your fuel supply is in the 3 - 4 psi range for carbs.

If you wire it as in Sir Andy's How To, does that keep the pump form running if the engine dies?

I can see the light at the end of the tunnel Group: Members Posts: 2,692 Joined: 3-February 03 From: Massachusetts Member No.: 224 Region Association: None |
The fuel pump how to thread works with cars that had D-jet. A separate relay was used with L-jet and those cars would need relays installed on the board.

Add a relay into the socket second from the end of the board closest to the rear of the car. |

Is there an easy way to signal the pump to shut off if the engine dies while the key is on?
