What is the proper or best way to plumb an auxiliary "L" tank?

 

please define "L" tank...lol

 

joe i think it maybe the tank contractors pu in the box and some hook it to the truck for the long halls the tank he may have if you look at it from the side it looks like a { L ] 6 or 8 inches is box high and the rest is under the bed toolbox

 

Good one cOOn! I got it. Yes, it is the type putz describes. Do you plumb a vent and return line? Or just let it gravity feed into the filler neck tube?

The best way to do it is to put in a pick-up tube, a return, a vent, a gauge sending unit and a 6 port pollak valve. That way you can select any tank and gauge from in the cab by just flipping a switch.

 

Do not fill by gravity thru the filler neck. It will over flow. Rodney said it best. I have an auxilary tank in mine but I have a pump in it so I can fill the taks when I need but I have to get out to do it. Not plumbed into the fuel lines. That way I can legally buy red fuel and illegally burn it. LOL
