Two cars with apparent fueling issues in this week. The GT6 ran perfectly well for 20 minutes when it would stop working. We found that the copper fuel line that was running along the engine block was causing a massive vapor lock when it got hot. Changing this fuel line for a rubber alternative and moving it away from the heat source should help. The E-type had some hard plastic fuel lines at the petrol tank, these weren’t sealing properly and allowing the pumps to pull air into the line. You could see the air bubbles in the glass filter bowl. Again fuel lines replaced for rubber.
