Fuel pump
Remember, it takes fuel AND ignition to make an engine burn correctly...a 1978 vehicle ( I own one) has had the wiring from battery/ alternator to distributor go " south" about 20 years ago.

I used a potentiometer to adjust the voltage BUT it only REDUCES the voltage, not increasing it. To adjust...- daveca

1991 Suburban 3/4 ton: TBI to Holley Sniper conversion - stupid, or worth it?

Good wire for repairs and/or rewiring circuits?
Its low voltage, any 300 V PVC insulation is fine. if its a leaker, use oil resistant insulation. Powerstream dot com for ampacity, or replace with same gauge, dont use solid wire, too easy to nick and crack/ break. Take out a second mortgage to buy wire... The wires not the critical part...- daveca

LED exterior light conversion! not going well :(
This bit the 1980s Honda Goldwing owners hard, install LED lights that draw almost no current and the voltage regulator freaked out. The 6 amp draw of the running lights was required to stabilize the regulator. LEDs require a minimum voltage drop to operate, the units will bd expecting 12-14...- daveca
