Fluid Quart Pump(142)

Match the pump to your container and the job you’re doing.

• Cap/bottle fit: Standard quart bottles often use 28 mm caps. If you’re using wide‑mouth quart or gallon containers, look for pumps labeled for those openings or “double‑threaded.”
• Fluid type: Many are designed for gear oil, transmission and differential fluids; some tools also handle coolant or brake fluid—check the product description for compatibility.
• Flow and control: Outputs like 8–10 cc per stroke offer controlled dispensing; longer hoses and a 3rd hand or secure fill tube adapter can help at hard‑to‑reach ports.
• Special adapters: Marine lower‑unit kits often include 3/8‑in, 8 mm, or 10 mm fittings.

Review specs and customer Q&A on the product page. Pickup and delivery options may vary by location.

Both move fluids, but they shine in different situations.

• Bottle hand pumps: Thread onto quart or gallon bottles. Common outputs are about 8–10 cc per stroke. Handy for filling transmissions, differentials, and other ports directly from the container. They offer steady metering and fewer parts to clean, though you’ll pump continuously.
• Syringe extractors/injectors: Self‑contained 200–500 cc tools that can both pull and push fluid. Useful for tight spaces, sampling, or precise top‑offs. They can move larger volumes per cycle, though thicker oils may require more effort.

Either style can work well; choose based on access, viscosity, and whether you need to extract, inject, or both.

Output depends on the specific tool and design.

• Standard quart bottle pumps: Commonly about 8 cc per stroke; some offer roughly 10 cc.
• Higher‑flow hand pumps: Certain models list around 30 cc per stroke, often for gallon or wide‑mouth bottles.
• Syringe tools: Rated by capacity per fill (for example ~200 cc or ~500 cc) rather than per stroke.

Actual flow can vary with fluid temperature, viscosity, and how quickly you pump. For thick gear oil, a lower‑per‑stroke output can provide better control, while higher outputs may help reduce time on larger jobs. Check the product specs on Walmart.com for the stated ratings.

It’s possible, but cross‑contamination is a real concern.

• Best practice: Dedicate one pump to each fluid type (e.g., gear oil, ATF, coolant, brake fluid) and label them.
• If reusing: Flush the pump and hose with a compatible cleaning fluid, then pump a small amount of the new fluid through to purge remnants. Allow parts to dry as appropriate.
• Keep brake fluid separate: Even small amounts of oil residue can be problematic in brake systems.
• Storage: Cap hoses, store in a sealed bag, and keep the tool with the same fluid family.

Always follow your vehicle or equipment manual for fluid specifications and service guidance.

Look for a pump designed for marine use and the right fittings.

1. Select a pump that threads to quart bottles and includes marine adapters (commonly 3/8‑inch, 8 mm, or 10 mm).
2. Attach the adapter to the lower unit’s fill port as outlined in your owner’s manual.
3. Use the secure fill tube adapter or a 3rd hand feature to help hold the hose in place.
4. Pump steadily until fluid weeps from the vent/top port, then follow your manual’s steps for reinstalling plugs.
5. Wipe up drips and recycle or dispose of used fluids per local guidelines.

A flexible, longer hose can make confined areas easier to reach.
