Fuel Pump Wiring

[cidsamuth]

Anyone have a wiring diagram for all leads out of the fuel pump under the back seat?

I want to add an inertia kill switch. Since the interior is stripped down anyway (track car), it would be easy for me to grab one of the lines at the pump … assuming there is a lower amp feed there that would kill fuel supply if cut?

Any idea the amps being pushed through pin #5?

You might check your fuse panel or invest in a cheap multi-meter.

I have the multimeter …. just hoping you had a quick answer so I wouldn’t have to spend time poking wires. Im looking to confirm if I needed to use a relay or whether the inertia switch could handle the current on its own.

Regardless, thanks for the wiring diagram; it helped a lot.

Sorry, I don't know without testing myself.

After looking it up:
In the under-hood battery fuse box, the fuel pump is controlled by the fuel pump relay.
The fuel pump fuse is 30A.
