Fuel pump mechanical, hif38 cars 1992-4

For 1275cc engines after 1990 on with HIF38 carbs.has a 5/16″ (8mm)inlet which makes it unique to this modelThe 1990-1 models of the Mini with 1275cc engines and HIF44 carbs use a AZX1817 mechanical fuel pump. Driven off the camshaft at the rear of the engine these pumps are generally reliable but when a diaphragm goes bad it can be very serious as often raw petrol/gas is pumped into the engine. This dilutes the oil and causes severe wear. For pre 1990 cars with 998cc use AZX1818 Fot later 1275cc cars with HIF38 carb use WND10005which has a 5/16″ inlet pipe
