We have had a PFM Unit on a 320hp 3208T caterpillar engine in our Pelin Columbia planing Launch for around 2 years (approx 1200 hours). There was evidence of bug in the sightglasses on the fuel tank when we first bought the boat. Due to the high fuel return rate this has cleared up significantly. The engine now runs and starts superbly and relying on a single engine installation reliability is paramount. The exhaust emissions are also noticeably cleaner. Our next move is to install a polishing system to rotate the fuel through our mighty PFM Blue unit while the boat is not in use.
Long story short, we would not be without it!
