Clunking Sound, Air Regulator, Fuel Regulator, Tracker Valve. 2009 250 ProXS Mercury Optimax DFI

My Fuel and Air Regulators were torn. I had a terrible clunking sound. Fuel was flooding my pistons. To get the fuel rail items replaced and tuned was about $1400.00. Rather than doing that to a 12 year old Fuel Rail, I purchase new and delivered for about $1650.00 including tax and delivery. A new fuel rail comes tuned from the factory. All appears good.
