I was thinking about what it would take to get dual tanks going on my M1008 CUCV diesel. My best idea right now is to install the second tank, then just plumb it up so I can use an electric fuel pump to transfer fuel to the main tank. In the cab I'd just need a switch to turn on the pump, plus a cheapo fuel gauge for the second tank - or possibly a switch to use the existing gauge and switch between sending unit signals. The things I haven't figured out are: 1) How to deal with the filler for the second tank without hacking the sheet metal. 2) Which pump to use. Needs to be self-priming and good for diesel. 3) How to get the fuel into the second tank, like exactly where to plumb it in. I can't remember exactly what's available on the sending unit. 4) How to source the brackets to mount the tank. Would the same L-brackets from the driver's side work? Anyone know if the frame is pre-drilled? Comments?
