John---

while I don't profess to know much about Bosch pumps at this point (haven't bothered to do the research....), I can tell you that if you want a pump that will feed anything you're building, Barry Grant is the guy to see.

Grant's fuel pumps are feeding everything from Pro Stock to Pro Mod.....His "mighty sumo" pump will support 750 hp--400pph, and the "king sumo" will support 2000 hp--1000pph. Both of these pumps are fuel cooled, low amp draw, constant flow, made specifically for efi engines. He also markets a regulator matched to these two pumps.

We run one Grant BG-400 pump with #10 AN lines on the quick 16 car, feeding a 572 CI BBC with 14.5:1 CR. No fuel delivery issues---ever. About twice as much HP as your twin hairdryer motor.....This is a tube frame car that regularly runs 5.30's in the eighth, low 8's in the 1/4.

As for fuel delivery, yes John, you're on the right track with going to bigger lines. Not just on the supply side, but also on the return. The larger lines will aid in cooling the fuel (heat due to pump and engine compartment temps). If further cooling is needed, there are coolers out there on the market.

(Grant makes no comment about fuel heat issues in his website at the moment....)

Mine will have the same set up as the Chevy II, with exception the pump will be a "king sumo".-----one of these days....!
