Hi Group, While this is not a specific 300 question, it deals with a mechanical problem we all are subject to. While rebuilding the carburetors on my 440-six pak engine, I noticed a gummy build up of varnish in the carbs. (I should have used Sta-Bil before storing the vehicle 4 years ago). The varnish comes off quite easily using Gum Out carb. cleaner. However, I'm sure there must be the same amount of varnish in the tank, fuel line and pump. Has anyone had any luck with a store bought varnish and gum remover that can be added to the fuel tank that would dissolve the sticky stuff, thereby cleansing the entire fuel system? Thanks for your input Vic Selvaggi in soon to be 100 + F on Long Island.
