I have a 51 gal RDS tank/toolbox aux tank, best thing I could have done, ordered it from Northern Industrial and installed myself, it is set up for a gravity feed so no extra
Cost for transfer pump. Installation was easy, it comeS with the RDS installation kit. Cordless drill, some fuel hose & hose clamps, I also installed a 1/2 ball valve
Between aux tank and factory tank for isolation. I also cut 1/2 thick rubber mat to cushion tank from truck bed.
The fuel gage reads full as the fuel gravity feeds the factory tank, when my gage starts dropping I know the aux tank is empty.
