Hi Randy -

Lotus Esprits have dual tanks and cross-over pipes. My S1 has a very small diameter cross-over of about 5/16" and it is too small to be effective - I still have to fill both tanks. The cross-over consists of a steel tube running across the engine bay with fuel hose connections to each tank. Later Esprits utilized a larger diameter cross-over pipe. I'm not sure of the exact size but it is an inch or less in diameter. This allows filling from one side with venting provided by removing the filler cap on the opposite side. Not sure I'd want to run a fuel line through the interior of the car - just my $.02.
