Default Electric fuel pump wiring

Hi all,

Does anyone have any pics of where their electric fuel pumps are mounted near the fuel tank and more importantly for me, how you have wired it and by what path?

Bit unsure as to where to drill a hole to get the wire to the fuse box area in the car.

No photo but I mounted mine on the framehead on the opposite side to the mastercylinder. I ran the wire along the same route at the wires to the mastercylinder rear brake lights.

One way to wire it - there are others.

You can use the oil light warning wire instead of the alt / dynamo warning light wire if you prefer - it works either way.

I am going to include a impact switch to kill the pump in the case of a mishap.

No real need for an impact kill switch if you wire up your pump through a relay as Dave suggests above. Fuel Pump will turn off as soon as the ignition light comes on. works for me everytime

I put another feed through a relay activated by the starter signal wire to get fuel pump working when its turning over ... as that can be a while after a long stand..,

Here's the two relay version if you want to do it that way - but personally I prefer the single relay and a prime button for simplicity, (as above) however I understand not everyone wants to drill their car for a push button.

have you put the relay in the fuse box or threabouts? Also where is your prime button located? Where did you drill the hole?

Thanks for your help people.
