12v pump mods with no power gain
Hey guys, im new to the forum. Ive got a 12v i did some pump mods (removed fuel plate, turned up star wheel and turned smoke screw in just a bit). I noticed no power increase and no smoke. Im not looking to dump smoke just want to get it to smoke so i can tune my afc. The boost lines that connect to the afc are new and ive got good fuel pressure from the lift pump. Not sure on the psi. But the lift pump defiantly puts out some pressure because i lost the supply line from the filter to the p7100 and when that went there was plenty of fuel coming out of that line. Replaced that line with a half inch fuel line. Im stumped on wat to check next. Any ideas????
