Fuel pumps in series help I have a Spectre EFI tank in my car with a Delco EP381 in tank pump which is supposed to be a 50-55gph pump at 58psi. I picked up an Aeromotive 450 lbs/hr pump which I plan to put inline just outside of the tank. Any opinions on this?
With the EP381 in the car I drop fuel pressure at about 70% TPS with the magnacharger only blowing 5psi. I want to blow 10lbs on E-85 here soon so I need a solution to the problem as well as greatly increasing my fuel delivery.

You are never going to pull more fuel through an internal pump. It can be a patch to help keep the pressure up but you will never add volume. If your pump is running out at 70% you need alot more volume. You need a bigger internal (or 2) or one large external sump fed.
