It is well known that the OEM LC8 fuel pump is a weak point in the design of an otherwise high quality piece of machinery. It uses mechanical contacts to provide "interrupt activation" of the Mitsubishi diaphragm pump. It is located in an area (under the front of the engine) that receives the worst that the environment has to offer and are subject to corrosion, pitting, and wear like all point activated electrical breakers. There are several fixes in the works by Forum members at this time. Take a look at what others have done and copy, improve, or come up with your own design to share:
