The 496ho in my boat seems to run real well however was talking to a reputable shop about upgrades (headers & tuning) and they suggested first and foremost to look at the existing fuel lines from tanks to IMCO fuel valve then from valve to the pump. He said to be sure I had 1/2" id not 3/8" id as I guess it's a common mistake on these 496 motors and he stated that making sure the fuel volume never has that little extra opportunity to drop via lack of supply was very important. Well my boat has all 3/8" lines so I'm getting ready to buy all the hardware and hose, but it has me thinking to go to AN fittings rather then the barbs and hose clamps, yea will cost a little more but will be prettier as well I feel safer down the line. Did some looking around and don't seem to be able to find pictures of any smaller Merc fi motors (377 scorpion, 496's, 8.2's or even 525's) running an fitting suit all seem to run barbs and hose clamps. Is there a reason for this or is it the fact most just do not care to spend the extra cash on such a minut thing
