0440007997 Bosch Supply Pump

This pump’s job is pretty straightforward – it takes fuel from the tank and pushes it up to the carburetor. It doesn't really create pressure, it just moves the fuel along. Newer cars use a different system with an in – tank pump that does the pressurizing, but this type of supply pump relies on the engine’s movement to work – typically, as the engine runs, a diaphragm inside the pump gets pushed and pulled, which draws fuel in and sends it on its way. Think of it like this – the fuel tank is your reservoir, and the carburetor is where the fuel gets mixed with air to actually run the engine. This pump is the link between those two. It’s a mechanical pump, so it’s driven by the engine itself, usually off the camshaft. Without it, the carburetor simply wouldn’t get the fuel it needs, and your engine wouldn't run, or would run very poorly. It essentially acts like a helper, constantly making sure the carb is supplied. If this pump starts to fail, you’ll notice if your engine is having trouble starting, or if it’s running rough, especially when you accelerate. You might also see a lack of power, or it might even stall completely. It’s not a part that usually gives a huge warning before going bad, so it’s good to address problems quickly. A failing pump can cause lean conditions, which aren’t good for the engine long – term. You can find a replacement pretty easily; places like Fixparts Online stock them, and honestly, it’s a relatively simple repair for someone comfortable working on cars. It's a critical component to keep things running smoothly. Built to endure: Supply Pump (MPN 0440007997) comes with a 12-month warranty!
