the problem was the pressure regulator, or rather the filter screens on the pressure regulator-
there is NO such thing. would be confusing to readers not familiar with these pumps.
upwind from the pump there is a "sock" style filter....downwind from the pump there is an automotive style inline filter. there is NO filter attached to or related to the pressure regulator. period.
Earlier this season I replaced the fuel pump assembly in one of my Buell's. When I turned the key on the fuel pump didn't sound right and would pump up slowly. John, (L.F.) thought it was a sign the fuel pump was failing and that it should be replaced. I followed his advice and did so.
The stock fuel pump inlet filter/screen/sock is fairly small. When I pulled the fuel pump assembly the sock was totally plugged. My problem could have been just the plugged up sock but as I has everything apart and doing the work myself decided to replace everything, (filters, pump, regulator and level sensor). Bought the sensor and seals from John and went with his suggestion on the pump. Everything's running great.
