I have a 1986 F150 4x4 302 EFI motor with dual tanks. I understand it has three electric pumps 1 in each tank (low pressure units?) and one on the frame rail (high pressure ?).

I am contemplating a switch to carb if I cannot get the EFI to run reliably. So, I am trying to find out the running pressure on the two in tank pumps and whether they could be used to feed a carb.

I know that the transfer valve is an issue too. I am wondering if anyone has tried this and how it turned out.



Thanks in advance

Chris
