Twin Walbro install(Question)
Twin Walbro install(Question)
I recently Purchased a Full Blown Twin Pump assembly and I became a little confused on were to source my Constant 12V source for the 2nd Pump. For the 1st pump I just ran the (+) (-) Source of the existing wires of the OEM Fuel pump harness. I already have the 2nd Pump Relayed to the StandAlone's negative Trigger switch. I searched and found the Twin Pump Install thread, but it was unclear on were to source the power for the 2nd pump.
So can I:
1) Use the same 12V source of the Fuel Pump Harness, but Ground the 2nd pump off a different ground source?
2) Just Run a wire from tank to the front of the car to the Fuse box directly to the 12V source?
Thanks in advance

You need to run a new 12 V line with high current wire (I used 10 awg). DO NOT use the factory harness for both pumps. I tried it and it creates a massive voltage drop and neither pumps gets proper voltage.
I ran a fused line from the battery to my relay which is mounted in the trunk, then to the pump.
