Going to relate the details of a recent experience for posterity and searches for future people.
I was experiencing hesitation and low power under 4-5000 rpm, regardless of throttle, and slightly less so when fully hot.
It was getting worse, and I chased wires, plugs, whatever I could find, but it was across both cylinders, so I suspected a clogged filter.
I let the fuel run low to aid draining the tank, and started hearing a hissing sound when the pump primed. Like spraying gas...
Drained the tank and dropped the pump assembly, and lo and behold, the fuel high pressure line into the filter had cracked due to age and extreme bend, and was cutting half the fuel pressure and spraying back into the tank.
All symptoms solved. In fact, its better than ever. I wonder how long it was cracking.
I was going to go nuts and start messing with things I ought not (TPS).
Hope this helps someone in the future!
