A tidy gasoline-approved mains kit with theft protection, but the Fill-Rite FR610H pumps faster for less.

GPI EZ-8 12V 8 GPM
#12 in 12V DCFull review
For small gasoline jobs like mowers, side by sides and generators. It costs only $85 less than the much faster M-150S, so most buyers should step up.
