Pros
- Runs continuously, so it can empty a big transfer tank without stopping to cool
- 25 gallons a minute, the fastest 12V pump here
- Brushless variable speed motor runs on 12V or 24V trucks
- 18 ft hose and an automatic diesel nozzle reach around big equipment
Cons
- Costs about three times a basic 15 GPM pump
- Draws 30 A, so it needs heavy wiring and a healthy battery
- Comes with a diesel nozzle; gasoline use needs a different nozzle
