External Fuel Pump Wiring

braindamage · May 6th, 2018, 08:40

Hi guys, just a quick question.

I had a quick google and couldn't pull up a comprehensive answer.

I've upgraded the external fuel pump, the original pump has a yellow and black wire running to it. Common sense says the black is common/ground and in turn the yellow must be live feed.

Is anyone able to confirm this for me, i've made assumptions before and seen some wiring on cars that defies common sense so just want confirmation, Thanks.

Hi,

In this case yellow is live and black ground, but always good to check.

If you had a multimeter handy you could check that black was ground by checking if it had continuity with any other section of bare metal presuming you can find some bare metal on a well maintained Volvo.
