This little pump basically helps move fuel – typically diesel, but sometimes gasoline – from the tank to the engine. It’s a manual pump, meaning you physically operate it, usually by hand – hence the name. It creates suction to draw the fuel up and then pressure to push it through the lines. Some are used for priming the fuel system after a repair or if the vehicle has sat for a while, others are used for transferring fuel between containers. There are different types, some are used for things like windshield washer fluid as well. Traditionally, especially on older vehicles or equipment, it was a key part of getting fuel to the engine. On newer stuff, it’s less common as most vehicles use electric fuel pumps. Now it's mostly seen in situations where you need to manually move fuel, or like I said, prime a system. You might find it on things like lawnmowers, small tractors, or even some older cars and trucks that have a gravity – fed system needing a boost. It can also be part of a fluid transfer kit. Well, without fuel getting to the engine, nothing happens. It’s like trying to run a furnace with no wood. A hand pump ensures a steady supply, especially when the engine can't pull it on its own. If it’s failing, you’ll notice if the engine struggles to start, runs rough, or won’t run at all. It acts like a shield against air getting into the fuel lines, which can really mess things up. Sometimes they’re pretty simple to replace, but you’ve gotta make sure you get the right one for your application. We have a good selection of hand pumps at Fixparts Online, and I can help you find the exact one you need if you tell me what you're working on. Suitable for every driver: Hand Pump (MPN 0440011016) includes a 12-month warranty!
