[Spridgets] Won't Idle

Facet brand pumps don't stop running when up to pressure.  They keep right on banging along.  It's not a "tick" like an SU pump either - very annoying.

This may suggest a problem with the float operated shut off valve. Were fuel lines blocked the pump would stop running as it would be up to pressure.

I recently had a problem with the ethanol in the gas plugging up the fuel system after leaving it sit in the garage for a few months without starting it.  I installed a new Facet fuel pump, but I can hear the new pump going constantly behind me like the tank is almost empty, but according to the fuel gauge it had at least a 1/4 tank left.  As long as I kept my foot in it and did not stop anywhere, it ran like a scalded cat.  That new 1275 that I installed a few thousand miles ago is finally breaking in.  I was going to replace the fuel tank. (I have a new one ready to paint and install), but I got it running by draining the old ethanol laced gas and filling the tank with 100 octane ethanol free gas.  I thought I cleaned the fuel system out of the ethanol.  It ran great for a while. It did die a couple of times, but started right up again and would idle, now I have to keep revving the throttle at the stop light to keep it running.  I hate this Kalifornia gas.
