I wouldn't drill the 2 1/2" holes into the fuel pump housing. The housing needs to stay intact to provide a steady supply of fuel to the pump under conditions when the fuel tank is low and you are braking or making turns. I have force induction running on E85 with a return fuel system and haven't had any issues for 6+ years. I will look for my notes and pictures if you would like. In the meantime if you're interested check out my showcase for a list of my mods.

Yes, I have my fuel pressure set 50 psi. That pressure works well for both 93 octane and E85 tunes using 1000cc injectors. Also, I increased the diameter of vortex jet port located were the return fuel line meets the pump housing. Purpose of the jet is to use the return fuel to draw more fuel from the tank to amplify the volume of fuel returning to the pump housing. Be carful when drilling the hole bigger because its pretty fragile plastic.
