Checked the pump valves , no signs of debris, seemed to work fine. Next test. Added some more fuel, warmed up on the slope. Pump started running almost continuously as before. Did 12-15kms around local roads, climbed a steep hill without issue. Stopped at garage to fill up, 7-8 mins, went home via an indirect route. Getting it backed into my garage requires some backing and filling, and just as it was almost done she died....couldnt hear the pump. left ign on, opened bonnet - no pump activity, filter almost empty. Pump was quite hot - not too hot to hold, but a lot more than warm. Broke electrical connection, reconnected, couple of pulses, stopped.
Pump doesnt like getting hot! Let it cool for an hour, pump ran again by itself. Going to try moving it further into the corner behind the lights, behind the washer reservoir.....
Stay tuned.
