e-fuel wiring

[diesel50]

looking for information on what wire gauge size is needed to wire up e-fuel system.

I'd imagine it depends on the pump you install. Stock super duty pump should be fine with some 12-14 gauge wire.

It is a stock SD pump.I would think that any replacement pump wouldn't have any affect on wire gauge size. What wire gauge from the pump to relay to oil pressure switch, battery power.......!

I used the same size on all of mine

 

[Dzl1691]

What size wire did you use ?

 

[old man dave]

Use 10/12 from battery and fuse to relay contacts to pump. 16/18 from key on power to relay coil to oil pressure switch. According to tests, wire sizing for the fuel pump side makes a difference in output. There's not much difference in price between 12 and 10, so don't cheap out like the factory does using 14 or less. The control wiring doesn't carry much current so using 16/18 is mainly to be more durable than anything smaller.
