A cork gasket should be in the inlet ring on the tank.

Moss part #293-600 "GASKET, gas cap (for original cap)" $1.99

For $1.99, the cork gasket is a lot easier to buy than it is to make. I believe that the cork is 1/8" thick, possibly 3/16". It fits tightly between the outer and inner lips of the tank opening. Soak the cork gasket in oil before installing it, so that you can squeeze it into position.

The lid has two cups. The outer one is spring loaded and presses against the cork gasket. The inner one fits inside the inner ring of the gas tank opening.

The release catch is held by a rivet and hooks against the tab in the lid. Perhaps a forum member has a catch for sale.

Some owners put a sink drain tail piece into the gas tank opening to create a baffle to keep gas from sloshing out. Other forum members can describe the process.

My car came with a rubber seal in the cap which I thought was original.
You learn a little every day.

My TF 1500 has a gas cap with a cork gasket but about a half of inch of the gasket is missing. How is the best way to remove old one so nothing falls into gas tank and what procedure do I follow to insert a new one? I will buy new one from Moss. How long does it soak in oil before trying to insert it. Thank you Ann M

I held a paper towel inside one side of the opening with my fingers holding it from below. Pick out the old cork on the side of the opening that is being protected by the paper towel. I used a hook pick, an ice pick with a bent tip, and a small screwdriver to pull and scrape out the pieces of cork. Dispose of the bits, then move to another section.

Don't suck out the pieces with a ShopVac because gasoline fumes will be sucked through the motor. Sparks and fumes could be bad.

Soak the new cork gasket overnight or as long as you care to do so. Just about any kind of oil. Motor Oil. Sewing Machine Oil. Etc.

Poke the new one in place with any tool that you have that will not puncture or cut the cork.

The new gasket stopped gas from sloshing out of my TF tank.

Holy Smoke Ann -

I just read your profile and vehicle register. What a wonderful story. You and your TF were obviously made for each other. Thanks for including your history and photo in your profile.

A New York forum member should remove and install the cork gasket for you ... just for the privilege of touching such a fine MG.

Have a great day,

Lonnie

My gas cap has a rubber O-ring like Declans.......... the outer cup spring part of the cap is real rusty and not much spring action happening. That may be part of my problem and that there is no cork gasket? I might try to free up my spring and see what happens.

The cup design has me confused ,,doesn't take much really,,,, how can the two cup areas form a seal with metal on metal. But then I'm no engineer confused smiley

Also check Abingdon Spares, their prices have been lowered to compete with Moss, and their quality is usually better. the also have parts that Moss does not have..

Purchase a home plumbing sink metal straight pipe with a flange at the top cut to 6" & insert into tank filler. this will keep fuel from sloshing out at the filler & also keep from filling the tank too high.

I believe the original TD/TF gas cap had a circular cork disc between the two metal discs (in addition the the cork ring on the neck). Most are long gone and irreplaceable as the metal discs are press fit and cannot be easily removed and replaced.

I think it is correct that there was a circular cork disc between the two metal discs. I drilled out the central fixing / rivet so they could be separated, and inserted a disc of heavyweight gasket paper in place of the cork disc, as I thought it would be more durable. Then I reassembled using a screw to hold it together - I guess that a rivet could be used to retain the look.. It appears to work well now that I have also fixed the spring clip.

Bumping an old post on Cas Caps

I have a new cork gasket, but the lid does not stay locked and is easily tripped hence smell of gas after corners.
Is there any way to strengthen the spring locking clip?
It is a tad difficult to see what is going on under the lid.
I removed the O ring, and it seems to be a more positive close, but prone to snapping open if touched or shaken hard. (pot holes)
Could it be hinge wear? Which does not look bad or rusty. Holes in the tank neck look round and OK too.
