pump. The pump features an integral bypass valve to recirculate and uid when the pump is operating
with the nozzle closed.
SKID TANK INSTALLATION
To mount the fuel pump on the fuel tank,
1. Attach the telescoping suction pipe to the tank adapter.
2. Extend the telescoping suction pipe to within 3” of the bottom of the tank.
3. Screw the tank adapter to the tank ange.
4. Install the seal and screen on the adapter and mount the fuel pump on top.
NOTE: Small amount of thread sealant should be applied to each thread to prevent possible leak.
