Hi Mike,i want to move the engine forward a bit more so that i can remove the lead,i will also move the exhaust duct forward as well,i am thinking of moving the uat up front and puting a small tank where the uat is now this way i can drain the main tanks with out running out of fuel.My tank troubles were do to the rubber bungs in the tanks one had completely fell to bits!!i have now installed the Dubro bungs which fit much better and give a good seal regards keith
