Sump VS. 5/8Suction tube
Ok, so im upgrading my fuel system next. I want to run 5/8 fuel line to my lift pump and was wondering if it would be better to install a sump on the tank or 5/8 suction line. Both are bout the same price for the LB7 because of the $60+ stupid bulkhead fitting on the pickup assembly. I hear talk of 1/4 tank problems with the suction tube, but was wondering bout clearance/ slosh issues with the sump? Also wondering about which lift pump to use. I have an 01 2500hd with 5" straights, aftermarket down pipe( full open "mouth" off the turbo) cold air and bully dog gt tuner. I also just purchased ATS boost fooler to install since i just found out the GT doesnt prevent the stock boost defuel. In the future would like to instal BD drivers side exhaust manifold. I have all stock fuel system, thinking bout porting to .125" rail fittings and shimming the FPRV and running 5/8 line all the way to the CP3. Truck only smokes a little bit when i romp on it in the extreme tune(which i only done once since i still have stock tranny) so i know i need more fuel before i start working on air(PPE boost valve, ported intake horn. Any ideas/input/opinions and anything else but whinning are trully appreciated!
