1995 6.5L electric fuel pump/oil pressure circuit
You should be able to energize the circuit by jumping from the large hot 'lug' located under the hood at the fuse box there. The cuirit / fuse is located there also, can't remembver the exact location , but it is labeled / in owners manual. My truck is also a '95 ( Turbo but shouldn't be diffrent.) I installed a relay from Kennedy to power the lift pump and it has it's own 'switch' to energize / prime the pump / fitler .
