Frequently Asked Questions

Q: What bottle sizes is this fluid pump compatible with?

A: This fluid pump is designed for standard quart bottles fitted with 28mm bottle caps — the most common size for automotive gear lube, motor oil, and transmission fluid bottles. Simply thread the pump onto the bottle cap opening and you're ready to go.

Q: What does the 3rd Hand Adapter do?

A: The 3rd Hand Adapter clamps and holds the flexible filling tube in position while you pump, keeping it directed at the fill port without needing someone else to hold it. This makes single-person fluid top-ups much easier and cleaner, especially in tight engine bays or undercarriage access points.

Q: How much fluid does each pump stroke deliver?

A: Each full plunger stroke delivers exactly 8cc of fluid. This consistent, measured output helps you fill to the correct level without overfilling — great for differential and gearbox fills that require precise amounts.

Q: Is this pump suitable for use with boats and RVs?

A: Yes! The 23.6-inch (60cm) flexible hose and PVC tube construction make this pump versatile enough for automobiles, trucks, motorcycles, RVs, boats, and ships — anywhere you need to transfer fluid from a quart bottle into a hard-to-reach fill point.
