clive i bow down before you, your advice was 100% correct, i filled the wrong tank with the good fuel the other tank was empty, so i had the tap switched to the empty tank :red:, anyway i took the fuel out again and put it in the empty tank and switched the tap to that tank, and back up and running again, i think the passenger tank may be blocked or bunged up so im sticking with the drivers side tank . thanks again for your help clive.
