I have a turbo TC with left engine low fuel flow at low rpm's when the engine is hot after a flight. My questions are first is the pump regulated internally or is it rpm related fuel pressure. Also is the pump sensitive to heat and output pressure lower when hot. On initial cold start my fuel flow is good and shows the same as the right engine at 1000 rpm's. After landing and taxing back the left engine fuel flow is low under 1 gph. There is a adjustment on the rear of the pump and wonder if that would bring up the fuel flow to the correct flow when it's hot. The TC pump is mounted to a oil scavenger pump and I'm sure that heats up the pump from the engine. The pump also has a air baffle attached to it but the air gets heated from the top of the cylinders near the oil cooler. Low taxing speed and the air flow is probably hot. -- Darrell
