ive bought a inline fuel pump to run off a fuel cell , can i just wire the green and yellow + wire to the live on the pump and the black wire to the neg on the pump.

i did some reading but i think ive got confusted when people started to use relays and stuff.

thanks

 

It depends on the current draw of the inline fuel pump, how much power does it need?

The stock fuel pump power lead is good to 20A if your inline needs mor current you will need to use a relay and a run a power lead, a fuse 14-12 gauge lead from the batt, to close to inline pump and connect to #30 of relay, connect #87 of relay to fuel pump pos.(+) using same gauge wire as you ran from the batt., connect the srock fuel pump power lead, [green/yellow] to #85 of relay, connect #86 of relay and the inline fuel pump ground to chassis ground.

Feel free to IM me if you have questions.

thanks for the reply, only thing is i dont know if its a 20 or 30 amp pump lol i bought it from a friend , ive had a look and cant see any were it says what amp's it is, is there any way of telling.

 

You could probably hook the pump up to a battery and use an analog ammeter inline with the circuit you make. I wouldn't use a digital meter. It's not a good idea to run a fuel pump dry either.

 

Then to be safe, run the power lead and use the relay. 94
