I am putting in new lines for my carbs. The hard line comes under the car, then connects to the old pumpt and filter. I am using the CB rotary pump and it's almost 12 inches long all in.
There is a mounting point for the fuel filter under the car, but if I try and mount the new filter there, then the lines under the car will be doing loops. Can i mount the pump underneath and then the filter above the tin? Is that a bad idea? Should I be doing this another way (other than moving the pump to the front). Let me know. Thanks! |

did you use the stock wire harness? if you look at the supplied plug end i think it only goes in one way with a white wire acting as the ground iirc. looking at the haynes (for a 73' usa, as your sig notes) it shows 2 wires for the fuel pump (#9) in the diagram . one labeled black/red and the other brown. the brown harness wire is the ground and connects to the white wire. other to the hot lead. i'm fairly sure. if not the pump will simply run backwards, and you will hear a gurggling sound coming from the gas tank. those would be air bubbles. if so switch the leads at the pump. btdt.

So I picked one. Easy enough to switch when I get to that point. In the home stretch. Very excited. Thanks again! |
