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.

Roughneck 12V 11 GPM
#14 in 12V DCFull review
A cheap diesel pump for occasional use from barrels. The missing safety listing and warranty make a GPI or Fill-Rite the better buy for regular use.
