172 Fuel Pump Wiring

[Daverb]

Can someone help me with wiring for the 172 fuel pump.

The connection is 4 pin - positive, earth, sender and something else?

Can anyone look up / tell me order of the pins? Wire colour? And what the 4th wire is for?

Thanks in advance.

I'll have to check to be 100% but the level sender has its own ground iirc as its not commoned up with the pump.

Ah so it will be?

Fuel Pump +
Fuel Pump Ground
Fuel Level Sender
Fuel Level Ground

Although maybe not in that order.

Really appreciate your help guys. Its for a cup car, I need to wire up a fuel guage so trying to find right wire.
