So I have the crane hi -6 wired directly to the accel coil , ran off points distributor w/o condenser. Drove it all day so far so good adjusting timing and carb little by little .the ballast resistor is still in car wired up . Fuel pump is surging -Holley blue w reg- fuel tank full so it’s not sucking air ,tank is new ..weld in sump new running #6a/n … u can hear the pump surge in like 3 second intervals it also has auto meter volt gauge surging along w it … I have the early 90 amp Dakota alt 1field wire to ground 1 to ballast resistor and heat wire to starter relay .. any ideas y it pulses consistently?
