Yeah not sure on that one. Cant run a machanical pump? you can get them in high volume and pressure. High volume for sbc is like 20-25 bucks new. I would avoid the 7-9 psi version unless you have a good regulator. Cheap ones either limit output or dont hold good pressure.
Heres a link to one just the first one to pop up in google. I have used these before with good results but usally buy from napa.

Fyi the other pump i mentioned is good for efi turbo system into the 500+ hp range. I dont think its the one for a carb setup.
