So I am new to the whole GT40 thing, figured I would gather some parts prior to ordering a kit. Well I, like a lot of people bought a 240 A12 fuel pump, took it apart, including the switch, cleaned everything, followed every post on this site. Put it back together, got the switch to work (checked with multimeter) with the assembly Manual I got with the rebuild kit, applied 12 volts and got got an intermittent staccato like sound, nothing binds, every spring has great return and every gasket replaced, but it doesn't last. I would first love to try a NOS switch prior to sending it for someone else to look at. Anyone in the states able to help?
