Marco's locking fuel cap

Recommended Posts

Hi all

Received one of these class bits of engineering today, fits like a glove.

Would definitely recommend.

Having received mine from Marco in 2018, I published a recommendation in TR Action 304 (March 2018).

A simple and effective device - wouldn't be without it now.

Hi Marco

I would be interested in a version of this for an early TR. I would buy 2 and my brother would buy one. Hope this encourages you to develop the product. Thanks for all your interesting postings.

Hi Jeremy,

it‘s yours now, so the title must be „my locking fuel cap“!

Great to hear you are pleased….

Ciao, Marco

True enough!

Hi Keith,

the latch of the lock goes in the gap between the caps body and the petrol tank and the TR4/4A cap has very relaiable dimesions.

They are all the same and so each lock insert fits in each TR4/4A cap.

Sadly TR2-3 look the same, but their body is made of 2 parts, the upper one screwed more or less deep in the lower part.

And I know of 3 different lenghts of the lower part. This is why the lenght of the TR2-3 fuel caps differ very much.

I made some for TR2-3 - but this was never sadisfying, I had a lot of returns and hassle, the last 2 of them I gave away as presents.

This is why I don't make them anymore.

The only way for you is to swap to a TR4 fuel cap, they look the same as the TR2-3 cap.

Sorry, Marco

Thank you Marco for your reply. I will have to find another way to keep the vandals out. Not keen to change the cap to later version.
