Hi all.   Could anyone please tell me what the outside diameter of a classic mini fuel filler neck measures?  Thanks.

Its wasn't off topic in the first place Richard, the question is all to do with a microcar. How perceptive of you , I did ask as I want to use a mini rubber over a Heinkel filler neck. You can either read minds or have been talking to Goggo ;)!

That would open up the use of several differing rubber mouldings as this is standard pipe section.

 The Trienkel used a sort of silver plastic material for at least part of the production run. The material is also found being used to make the hubcaps and prettily badged oil grommet on later chain-cases with the Bakelite type cover plate. These were intended to be fitted warm when the material is pliable as it is pretty rigid at normal room temperature. I have several old ones but they tend to discolour. In the Trienkels case it unusually has the fuel tank inside the main body of the car. The seal thus needs to be water tight or the bottom of the tank resting on soft material rusts out with the body floor below. Since this sits above the engine a nice hot steamy bath of water each run out is just the job for naff node major. Pin hole leaks on Trienkel tanks are a well known problem, and this is why. In most instances the tank neck grommet does not need to be 100% water tight as it is not entering the body and/or has a drain trap to collect spilt fluids and void them neatly, not so the Trienkel. This is why the Treinkel tank and grommet are a tricky thing to fit correctly. Not only has the grommet to be inserted with the flange in place and the neck through, a stern battle, but then the whole thing needs to be centred. Despite the body having a slot for the fuel tap thread to poke through into the engine bay you will be surprised how often it is a struggle to get good alignment, especially if the car is a restored one and accuracy has been lost. In my experience most restorers do not bother to mount the grommet correctly and pass the problem on.

So I did! That was just to confuse you! :D   The questions remains though, what is the diameter of a classic mini filler neck? That's all I need to know. If Goggo is reading this how about stepping out of your front door with a pair of calipers and measuring yours? There doesn't appear to be any in my neighbourhood.

Always willing to help bob but just a thought - if you want a rubber to go around a heinkel petrol tank neck why not be controversial and try a heinkel petrol tank  rubber ?  :D

Because the heinkel neck isnt going to protrude out of the body work, a seperate neck will that has to join up with the tank neck. Simples!. . The neck rubber situation resolved its self this morning, I found a neck from an MGB which is 2 1/4 inches od and the mini rubber I ordered arrived today which is a nice tight fit over it, I just have to find the right bends to join the two now.

Start worrying if there is stuff going on it that you don't know about! Pesky Bing Fairys move in or something.

I was going to suggest that with the MG pipe you might need to wind your neck in but then realised what I think it might be for. All very interesting.

And I was blaming the  Dellorto fairies for moving stuff around, spend an hour searching the floor the other night for a  woodruf  key that I dropped, spotted it immediately the next morning sitting on top of an oil can, must be the garage gremlins! The other year I dropped a small theodolite component, searched everywhere to no avail, ended up making a new part. Went indoors after a long day, removed my boots only to find the original part wedged in the tread of my boot!  >:( >:(

About winding my neck in, people are always telling me to do that, keeps it off of the block!
