I have been seeing indicated fuel pressures (9 - = 13 PSI) on=20 my VM1000 that are too low for the fuel servo (requires around 20 PSI) = to=20 operate at - but it continues to operate.

So after checking and modifying the fuel lines = (changed=20 from series to parallel for the boost and mechanical pump), removing = the=20 mechanical fuel pump and having it checked out at the manufacturer, we = decided=20 to just replace the fuel pressure sensor - figuring it would be under = $100 to=20 replace.

I called JP Instruments and got a quote of = $650. Holy=20 crap.

The technician told me I could field-test the = sensor and=20 that it has an output of 1mv per PSI input. ie 5 mv for 5 PSI, = 10 mv for=20 10 PSI, 50 mv for 50 PSI etc..

Does anyone out there want to sell a = working-but-not-using=20 VM1000 fuel pressure sensor (the higher pressure one) for fuel = injected=20 engines?

Does a guy have any options or FP sensors other = than VM1000=20 brand that put out that kind of output?
