A key element of the fuel system, this mechanical fuel pump 17/402000 by GX-AFTER is a low-pressure lift pump. It fits a wide range of JCB machines (e.g., Loaders 426, 436, Fastrac 1115, 1135), as well as many Massey Ferguson, McCormick, and Landini tractor models equipped with 6-cylinder Perkins engines (6.354, 1006 Phaser, 1006 series). Its job is to draw fuel from the tank and supply it under constant, low pressure to the injection pump.
GX-AFTER is the smart choice for your machine. We provide high-class replacements that combine excellent quality with an attractive price. Each part is carefully verified to ensure full compatibility and reliability you can depend on.

The list above is for reference. Due to the vast number of compatible machines, confirming the engine type (Perkins 6-cyl.) and pump mounting dimensions is key.
To ensure the trouble-free operation of the new pump and to protect the injection pump, we strongly recommend replacing the fuel filters during installation. Contaminants from the old system can immediately damage the new component.
A failed lift pump leads to fuel starvation and sudden engine stalling, which is dangerous during operation or travel. Furthermore, a ruptured internal diaphragm can cause fuel to leak into the engine oil. This dilutes the oil, causing a loss of lubrication and, consequently, engine seizure.
The 17/402000 mechanical fuel pump is a diaphragm pump driven by a cam on the engine's camshaft. The pump's lever rests on the cam, which moves the diaphragm to create suction, drawing fuel from the tank. It then pushes the fuel through the filters to the injection pump. It also has a lever for manual priming (bleeding air).

No, this is a mechanical pump that mounts to the engine block. It has an internal lever that is driven by the Perkins engine's camshaft.
This is a critical mounting dimension. It is the distance from the mounting face (flange) of the pump to the very end of the lever that contacts the cam inside the engine. It must be precise to ensure the correct diaphragm stroke.
It is a very common cause. If the manual primer has no resistance or the engine stalls under load, a worn diaphragm in the pump is the likely culprit. Other causes include clogged fuel filters (including the tank strainer) or an air leak in the fuel lines.
