Hi lads and girls, I am going to put a direct feed from ignition to an inline fuse then to a rocker switch then straight to my fuel pump, then earth it to the body, my question is what ampage wire should I use including fuse and rocker switch ? for my RST S2

Thanks
John

 

Firstly you should run any fuel pump via a relay.

Why do you want to run the pump off a rocker switch ? Why not just have it activated by the original fuel pump trigger ?

 

This what last owner was going to do, I think the relay system is no good, it just means I prime the system with a switch then on start up flick it back on again.

As said already the pump needs to be wired via a relay.

 

You want it wired through a relay and you'll need 30amp wire. A Bosch 044 runs at about 12amps and locks out at 18amps IIRC so 30 amp will be fine.
