I don't have a gauge to do it, so no I have not. I did run a hose into a can from the pump and ran the motor for about 10 seconds giving her a few med revs and it pumped about a half a pint of fuel. That is the only test I have done. I need to check the pressure, that friggin rebuilt pump may be it. The vacuum side doesn't work properly as the wipers still slow at throttle so there certainly could be something wrong with the pump it's self.
