your an electrican there not ! that why they missed it . when it is an electrical problem in the car body wiring the dealership is not the place to go.

well before you stated 12 volts at the pump ..this may be a bad ground connection.

pinching the return getting that much higher pressure your good with the wiring jumped. also the 6 amp draw sounds good.

now you got to find this voltage drop or bad ground .

loose fuses [bad socket] other thing like this will do it.
