Aircraft; Human Factors
I was making a precautionary return to the airport after experiencing a decrease in fuel pressure on my left engine. In the descent phase to ZZZ the left engine began running worse and worse as I descended. I activated low boost on the left engine to keep it running. I was able to keep the engine running until landing by a combination of low and high boost and manipulating the throttle. On roll out; my right engine idle was low and in an attempt to keep it running I hit low boost and pushed the throttle up; but it died anyway. Managing asymmetric thrust and keeping the left engine running so I could clear the active runway and not shut the airport down; took my full attention. I did not turn the little boost off of the right engine until I had cleared the runway and by then the system was pressure charged and porting fuel overboard.In retrospect I should have feathered and secured the left engine and concentrated on landing and clearing the runway. This would have reduced my workload.
