Here at Power Driven Diesel we are proud to offer the best in-cab fueling control for mechanical trucks on the planet! There are other kits available that offer max fueling in-cab adjustments, but not with the level of adjust-ability our kit offers. Not only does our AFC LIVE offer finer adjustments to max fueling, it also is the only kit that offers in-cab adjustment to the rate at which the fuel is applied. Before our kit the only way to adjust the fueling rate on a P-Pump truck was to adjust the star wheel in the AFC. Now you can set it to advance slowly for better smoke control and fuel economy or let the rack travel fast for ultimate power. All this is possible in-cab with the twist of a knob!
