If you need to remove the tank, you will need to empty your trunk and remove the back-board whigh hided the tank. The you will need to remove the interior padding for the rear seat. Then you remove 4 bolts holding the tank straps down. Then you will have to remove the chromed gas tank filler cap. This is easier on a late TR3A (after Comm. No. TS-60000) but if you have the earlier type you will probably have to cut through the rubber hose just below the filler cap to remove it all. See the attachment . It's a late TR3A TS-81551-L.
