Just wondering what everbody are using for a gasket for the petrol capp on an M20. I tried a search, but really found nothing. I remember someone saying that Robb had use some old leather. Is there an off the shelf product?
Cheers,
Dave
I use a couple of things depending upon what is available at the time
The absolute best was 75% teflon sheeting which is a foam. slightly harder than a thong rubber ( the ones under your feet for those with funny minds ) which I used to get scrap fom a local factory
Next was cotton insertion buytl rubber , but it too comes in a couple of densities and it must say "petrol safe " or something similar
Down here you can not use cork sheeting unless it is whole cork because the solvents that get put in out fuels ( which are nothing like petrol ) attack the glues used on ground cork sheeting even buytl cork sheeting and they crumble away after a time .
I am using a viton flat flange gasket ring and this is working well for many years already. Leather dries out in months and cork shrinks quickly is my experience. Really happy with viton and can recommend.
In NL we can buy these at technirub.nl at 6 or 7 euro a piece.
Yes that Viton is very expensive stuff. I bought a small square last year to replace petrol tank corks. Yikes!
But as the saying goes. "The cost is forgotten long after the quality is felt"

PS I was holding and selling stuff for the late Rob Nortier, which included a load of his leather, oil and petrol cap washers. Dave Plumb has that stock now.
Mark it would be handy for lots of guys to be able to purchase these tools again. I sold out of clutch nut sockets before I passed the rest to Dave. Which was unfortunate for me as I broke one of the castellated teeth off mine and had to get the castellation's re cut by a local engineer. It works just the same but is about 1/4" shorter now. Otherwise I have all the tools if you want to borrow them. Ron
Thanks for the offer Ron, but I think it would be easier to change the designs to suit my machines.
Though readily available, I will make the nuts as well to ensure a good fit.
The nuts will last longer being make from better materials.
Off topic Ron, or anyone else for that matter.
I'm looking to borrow an excellent condition or NOS 66-6096 adjuster cam.
