e:: Some OEM’s offer a fuel tank option which provides three auxiliary fuel fitting connections. With this option, the
fuel pickup tube and adapter plate are not needed. Simply route and connect the APU’s fuel supply and return
lines and the heater’s fuel supply line to these fittings. Always check your fuel tank for these fittings before
installing the fuel pickup tube or adapter plate.

IMPORTANT INSTALLATION TIPS
•
Identify and mark APU FUEL SUPPLY pickup tube for reference later.
•
Remove protective caps from ends of pickup tubes prior to installation.
•
Do not apply any type of sealant material to fuel pickup assembly. Doing so will result in plugged fuel lines.
1. Locate auxiliary FLS mounting flange and block off plate on tractor’s fuel tank. Remove block off plate and clean
surface area of all dirt, grease, etc.
2. Install adapter plate 10-379 (counter sunk holes facing up) and the gasket. Secure with the supplied screws and
torque to 90 lb-in. (10.2 N•m) maximum.
3. The APU diesel engine fuel supply tube is 24” and heater fuel supply tube is 23”.
a. Measure and cut APU diesel fuel supply tube 2” shorter than fuel tank diameter.
b. Measure and cut heater fuel supply tube 3” shorter than fuel tank diameter. The heater fuel supply tube is
identified by not having a fitting.
4. Loosen and slide the hardware to top of the pickup tube assembly.
5. Spread pickup tubes approximately 12” apart then squeeze pickup tubes back together and insert tubes and
bushing into hole of adapter plate.
6. Tip back-up washer and insert into hole of adapter plate.
a. With back-up washer on underside of adapter plate, thread nut onto bushing and hand tighten.
b. OPTION - Install supplied fuel pump bracket for fuel heater.
c. Position pickup tube as needed to facilitate fuel line connections and tighten nut to 16 to 18 ft-lb. (21 to 24 N•m).
7. Install supplied warning nameplate onto fuel tank in a visible area near fuel cap.
