Plus 2 Fuel cap leaks

Guys & Gals, I had the dreaded leak and searched the forum. An old post between Gareth and Steve has the answer with the secondary seal.

I was concentrating on the big seal and in the past missed the bit about the secondary one (behind). I drilled off the rivet top to remove and get at it. Then drilled and tapped a fitted a small screw so that I could refit all together. Then I played about with a piece of soft fuel hose to make the secondary seal. I took the filler neck off and kept filling it with water (up side down) to check that I had a seal. Need to get some tension! About 1/2 to 3/8 seems to do it. Yes I know they still make new ones in Brirmingham (same manufacturer of old) but I was sick of getting my wallet out.
No fuel leaks now with ?40 worth in the tank. Jobs a good un. More MPG and no nasty streaks
PS I will cough; I was unaware that there was a seal behind the flat disc. A lot have rotted and are not even there (40 yrs etc). I saw one that had that old cotton braided fuel hose that you have on you classic Suffolk Punch. It was as hard as hell and must have been there from the manufacturer.
Can post photos if required.
