Hey guys, my second stock pump is finally slowly giving out. I'm looking for a new fuel system recommendation that can hopefully work now and in the future when I go FI (shooting for 550-650whp). The car ('99 Firebird) is on stock pump, wiring, fuel rail, and lines, with a forged 347 (42lb/hr Lucas/Delphi injectors) currently making 355rwhp/350rwtq through a stalled [locked] 4L60E w/stock cats. Will I need to add a return line or route a new larger-diameter supply line? Looking forward to any recommendations.
