Starboard engine burning 50% more gas than port!!!!!!!!!
I just fix this issue I had for a while... signs are not running smooth at idle, unburn fuel coming out the exhaust, burning as much as 50% more fuel, white smoke, fuel pressure at fuel rail 45 psi not running, 90-100 running. no loss of power! the problem was on the fuel cooler generation 3, bad fuel pressure regulator clogged with paint from inside the cover where the fuel pumps are. solution: I replaced the fuel pressure regulator, took the cover out and cleaned all the loose paint with a steel brush, I put back together now it runs like new. I hope this is useful to other captains. I have mercruiser 6.2l horizon.
