I just purchased an EFI 351w from a 1995 F250 to install into our 1979 F100 shop truck. For those that have tackled this swap, and used a stock fuel tank in the rear behind the axle, did you install a low-pressure pump in the tank and a high-pressure pump on the rail? Did you use stock pumps from the donor truck, or aftermarket?

Second, where did you install the PCM?

Third, which (if any) headers did you use?

Fourth, did you eliminate the smog equipment?
