Mechanical 320/07201 fuel feed pump by GX-AFTER. This is a key low-pressure system component, dedicated exclusively to JCB machines equipped with proprietary engines – DieselMax and EcoMax (installed from 2005 onwards). The pump is responsible for drawing fuel from the tank and delivering it to the filter and high-pressure pump.
GX-AFTER products are proven replacements that provide fuel flow parameters consistent with OEM requirements. The robust diaphragm and seals are resistant to modern Diesel and Biodiesel fuels, guaranteeing long service life.

Note: Does not fit older JCB machines with Perkins engines (different pumps are used there, e.g., 2 or 4 bolt).
The pump is supplied with an O-ring for sealing the connection to the block. When replacing, we also recommend changing the fuel filter (e.g., 320/04133) and checking fuel lines for tightness.
A leaking lift pump can cause diesel fuel to enter the engine crankcase (oil dilution), risking engine seizure. Regularly check the engine oil level and smell.
Pump 320/07201 draws fuel from the tank and pushes it to the injection system.
