simple system,
pump starvation or bad pump. 22Rs don't have a fuel regulator.
so it's filters or pump. that's all there is to this fuel supply system.
k, it could be a leaky supply line to the pump. but you'd likely smell fuel.
check all external filters and the in-tank sock filter. or replace pump. i would pressure test the pump b4 i dropped a tank to check the pu tube filter.
