[Roadsters] Stock locking gas cap

[Pat Horne]

Easiest way is to open the trunk, disconnect the vent line from the filler neck, remove the clamp from the filler neck to the rubber filler hose & work the filler out from the body. Once it is out you can reach the screws on the bottom of the cap & disassemble the lock from the bottom.

Hey, group –

Having just cleared the last of the stuff stacked on top of my 1970 2000 Roadster hangar queen, SRL311-13291, I pulled back the car covers to open the trunk and to take a look down into the fuel tank. Problem is, the locking fuel cap doesn’t seem to want to unlock.

How far does the key turn to unlock the gas cap? Mine goes about ⅛ of a turn before hitting a hard stop. I squirted some Teflon spray lube into the lock and around the edges of the bit that turns – no change. Of course, I don’t want to apply too much force, so I may just wait and see if the lube loosens things up over time.

I have been clearing out my garage on and off since retiring in June 2024, and am just about at the point where I can get around to both sides of the car and the front and rear so that I can assess it and, with any luck, start working to get it back on the road.
