Replacement HPFP Diaphragm and Top Rings for BMW Phantom V12 Bosch High Pressure Fuel Pump 2 BANKS

BRAND NEW

This listing is for Replacement Diaphragms and Top O-Rings for 2 Banks
Common Problems/Symptoms:
The high pressure fuel pumps in V12, N73 Engines fail which causes the car to stall and cut off while driving. If you turn the car off and start it back on it may start back up and run again, but it will continue to stall and cut off. Some mornings you might have long cranks. This is one of the most common problems in BMW 760Li, 760i, Rolls-Royce Phantom which are fitted with V12 N73 engines. The cause of this problem is a failed High Pressure Fuel Pump Diaphragm. The dealer might tell you to buy high pressure pumps because the fuel HPFP pumps need to be replaced at around $3000 per bank/side. If you buy used ones you might end up with the same Problems. The OEM Diaphragm looks like one piece but it is two diaphragms sandwiched together in one pump. Just like the OEM diaphragms we will install the diaphragms in pairs.
