Non Genuine version mechanical fuel pump. Brilliant aftermarket alternative for cars pre 1990.
Drives off the camshaft at the rear of the motor. These pumps are generally reliable but when a diaphragm goes bad it can be very bad as often raw petrol is pumped into the engine. This dilutes the oil and causes severe wear. All minis except for 1990on versions with either the HIF44 or HIF38 carb.
