Fuel pump recomendation

I have a 1979 F350 with a Holley carburated 460. I’ve installed a custom fuel tank at the rear of the frame and now need to run fuel line and install a fuel pump.

I cannot use the typical engine mounted pump due to lack of space (power steering and AC pump). The tank manufacture recommended a Carter in tank pump but they appear to require fairly complex fittings and a full return system.

I want to avoid that complexity. What are my options? Can I install an electric in line pump outside of the tank? What model is recommended? I do have a regulator to install in the line.

Thanks for the direction!

Yes, you can install a fuel pump inline. This one should be a low pressure unit. Also, you will want to have an oil pressure cut off signal go to it, so it doesn't keep pumping if you get in an accident.

I know you don't want to mess a mechanical unit, but Edelbrock makes one that supplies 5 psi to the carb, eliminating the need for a regulator. You will love it once it is in. If you remove the oil filter first, the replacement goes much easier.

I just finished the writeup for my electric pump conversion. I used a Carter P4070. Here's the thread:

An inertia cut-off switch is what would kill the pump in a collision. An oil pressure cutoff switch only cuts the pump if the engine stops, which may or may not happen. An oil pressure cutoff switch must be installed at a minimum; an inertia switch is a highly-recommended addition.
