The contamination that is mentioned that ‘sticks’ the small valve in the HPP, is the fact that Diesel is in fact a wax, that when warm, is liquid. When it cools down, it returns to a wax. Us old time truck drivers know all about this, as we used to light a fire under the fuel tank if in the cold winters we used to have in the 50/60s, the engine would not start. Ahh the good old days. AlThough not cold now, it could have been caused by old diesel still in the HPP, sticking the valve.
