2. One (1) electric rewind switch in weather-proof box mounted to be accessible from the driver’s side of the unit within reach of the hose reel.

3. Capacity of 100’ of 1” inch Boostlite (or equivalent) hose.

4. 1” NPSH riser

5. Two (2) chrome, high-style outriggers, one each on the passenger and driver sides of the truck, main direction of pull will be to the passenger’s side.

6. Must have manual rewind option accessible from top or rear with manual rewind handle mounted via a bracket.

7. Remote hose reel button on 10’ cord that can reach both sides of truck.

BOOSTER HOSE

1. 100’ of ¾” diameter Boostlite (or equivalent) light weight hose with 1” NPSH field-repairable couplings.

PLUMBING

All valves must be full-port, ¼-turn, brass ball valves rated to 500 pounds per square inch (PSI). All valves must be labeled per valve labelling standards outlined in the National Wildfire Coordinating

Group (NWCG) Water Handling Equipment Guide (PMS-447-1, NFES 1275, October 2003). All plumbing is to be rated at 500 PSI. A check valve shall be installed on the discharge side. Pump shall draft through a Gruvlok brand or equivalent anti-vibration coupling.

The pump shall be pre-plumbed as follows on the suction side:

1. 2” three-way valve extending to the passenger side of the pump platform for drafting and/or tank to pump
