Fuel Pump Extractor | Wide-Mouth Bottle Adapter | Gear Oil Fluid Change

This automotive hand fuel pump screws straight onto standard quart containers and wide-mouth gallon jugs. It pushes thick fluids through a flexible discharge tube directly into tight access ports. It eliminates spills when servicing gearboxes, differentials, and lower marine units. Features and Benefits - Dual-threaded container cap - Screws onto gallon jugs and wide-mouth quart bottles without leaking. - Flexible long reach fill hose - Routes thick fluids into tight filler holes where funnels cannot fit. - Positive-displacement piston design - Moves heavy lubricants like gear lube and transmission oil with minimal effort. - Removable pickup tubes - Adjust inside the bottle to pull out fluid all the way from the bottom. Applications - Refilling rear differential housings and manual transmissions under cars and trucks. - Servicing lower unit gear lube on outboard boat motors directly from lubricant containers. - Adding transmission fluid, power steering fluid, or transfer case oil in tight engine compartments. What It Is This hand fuel pump is a manual siphon unit designed for automotive fluid transfers. It features a wide-mouth bottle adapter that fits standard gallon bottles and wide-mouth quart containers, allowing you to draw fluid directly from the source bottle without mess. The manual siphon mechanism transfers viscous lubricants and lighter fuels safely without the need for an electrical supply. It is an essential service tool for workshops and garages, providing a controlled, mechanical method for moving fluids into hard-to-reach vehicle reservoirs, gearboxes, and tanks. Key Uses & Applications This pump handles automotive servicing jobs involving gear oil, engine oil, and fuel. Common uses include: - Dispensing heavy gear oil into gearboxes, differentials, and transfer cases from wide-mouth containers - Topping up engine oil in awkward engine bay locations - Emptying lawnmower, generator, or vehicle tanks using the manual siphon action - Transferring fluids cleanly between gallon bottles and vehicle reservoirs The adapter secures directly to the bottle neck, preventing spills on the workshop floor during servicing. How to Choose Select a manual siphon pump based on fluid compatibility, container fitment, and your specific task. Ensure the unit is rated for your target liquid, whether that is thick gear oil or light fuel. When planning how to use a siphon pump for servicing, confirm the bottle adapter matches your fluid containers, such as gallon or wide-mouth quart bottles. For those learning how to siphon gas with a hand pump, position the supply container higher than the receiving tank, secure the inlet line beneath the fuel level, and prime the manual mechanism until gravity takes over the flow.
