GPI G20 12V 20 GPM with Filter
#3 in 12V DCFull review
The most complete 12V diesel kit short of continuous duty: filter, auto nozzle and long hose. Worth it for anyone fueling common-rail diesel equipment from a field tank.

3.8/5
For fleets and farms that fill big diesel machines and must track every gallon. Without that need, the FR4210H does the same pumping for much less.

- Limited lifetime warranty on the castings, with 5 years on the motor
Cons
- Over $900, close to the price of a continuous duty pump
- Must rest 30 minutes after each 30 minutes of running
