Fuel Tanks Dual tanks are recommended

Minimum of 200 gal for truck and grinder combined use, if off-road fuel
is allowed for truck use in this application.

Minimum of (1) 150 gal and (1) 50 gal tanks if off-road fuel is not for
truck use.

Minimum of (1) 50 gal min if optional 211 gal truck style tank is selected
(see fuel system setup instructions for more information)

Fuel System Setup Methods
Method 1 – Tanks should be connected with a minimum of ½ in crossover
fuel line with quarter-turn shutoff valves at each tank. Grinder and truck will
share fuel source. DO NOT tee off of truck supply lines, this will un-prime
the truck fuel system. This setup is recommended only if local laws allow
off-road fuel use in this truck in this application.

Method 2 – Truck and grinder will each use a fuel tank dedicated to their
separate operation. It is recommend that the tanks be connected with a
crossover line with shutoff valve so the truck source tank can be used for a
grinder reserve tank.

Method 3 – Truck is equipped with one tank for the truck engine on driver’s
side. An optional 211-gallon tank will be installed on the passenger side.
Adequate space will be required under truck cab for the tank.
