Amen,,,,I remember when the high pressure fuel pumps came out on the N54 engine,,,and we were replacing them everyday,,,,I remember I put a new one in a car,,,,,and went on a test drive with the new fuel pump,,,,on the test drive the new fuel pump failed and left me stranded on the test drive,,,,had to have the car towed back to the dealer and put another fuel pump in the car again. 1S 1155 9-35432 18-8868. I believe you need a new fuel pump. This “Next Generation” Safety switch is designed to protect your engine from a “lean” condition caused by low fuel pressure. Low Pressure Fuel Pump, Small Displacement - This is the same pump used in our motorcycle and other "Power Sports" kits. The same fuel pump is also used on the 4. 60 GPH @ 7 PSI; 12 or 24. Example- A single turbo 135 we put together ran out of 93 pump octane at only 17psi. Its output pressure is not adjustable. Situations where a PCV can be useful in pump metered systems include engine decelerations when a rapid decrease in rail pressure is needed, at low load and idle when injector flow requirements are low and as a safety device to relieve excessive pressure and avoid damage to the fuel injection system. It's imperative that you know the pressure going into the carb in order to properly tune, diagnose, and troubleshoot any fuel delivery problem.
