Forced induction fuel system

I've got a pair of big block AVS carbs for my 6-71 340, and I'll be running a boost referenced carter mechanical fuel pump.

Mild boosted engine, 6-7 psi, with methanol injection and boost proportional timing retard.

The pump is simple, you add a steel tube to the open hole in the side of the pump body and connect it to manifold pressure, as the boost rises, so does the fuel pressure. The meth injection can be assembled/pieced together (or you can buy a kit) I'm gonna just get the kit. But in the meantime my Accel 300+ & 375+ Ignition system handles the boost retard and such.

If I go much higher than 6-7psi you can bet I'll be getting an electric pump and boost referenced regulator to replace the mechanical pump
