Re: Burning up electric fuel pumps...
As stated, I bet a return line fixes you right up, plus you will need the proper pressure regulator (also as stated).
I put Accel DFI on my '68 and I plumbed the return line using an additional steel line, which I routed into the filler neck with a 90 degree brass fitting. Works real good.
I also mounted the fuel pump using a bracket mounted on rubber isolators, then I wrapped Dynamat around the pump (only the clamping area) itself, so that when I tighten the stainless hose clamps, the clamps are against the Dynamat material. This reduced the fuel pump noise to almost nothing. Some of those electric fuel pumps can get really loud when mounted right to the chassis!
