I have a 06 puma with dual rear tanks. The drivers side tank is not picking up fuel while the passenger side will. Ive already had this problem once so this is the second time Ive had the gas tank out. First time took the gas tank out checked everything. Installed it hoping for the best no good. Blew air from the gas line back into the tank and it worked for about a year. This time I was extra careful to check the pick up line inside the tank for trash or a loose place to be getting air. Also checked the fuel line going to the value for air leaks. Found nothing again. Anyone ever had this problem or know what to do to fix it.
