A strong all-round 12V kit: faster than the 15 GPM pumps, hands-free filling and theft-resistant. Pick it if you fill several machines a day.

GPI’s heavy-duty mains pump, a match for Fill-Rite’s FR700 line with more pressure. The NX25-120 adds continuous duty for about $160 more.

The best value 12V pump for a pickup tank: UL listed, gasoline approved and backed for life, for less than a Fill-Rite FR1210H at most stores.

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

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.
