Petrol tank neck size

Hi all, I recently found a hole in the petrol tank on my 81 bus.
So I purchased a replacement petrol tank, but found the hole where the filler goes is a smaller size 50mm. I am unable to fine a replacement tank with the larger hole 70mm to accept the metal filler neck.
I am thinking I can just buy the 50mm filler neck which I think is plastic and associated grommets.
Has anyone been through this issue or have any advice ?

Thanks in advance

I swapped our knackered late one for an early one and back again ... you swap the tank, neck and flange ( :oops: ) there's a write up in the Wiki on how to do it but the hardest job is undoing the collar round the flange ( :oops: ) and getting the breathers back in the top of the tank grommets.

Enjoy ! :rofl

Ian.

I can side with Ian on that one - the breather pipes/expansion pipes are a pig to put back in - make sure the tank is totally empty when you lower it as they are heavy when your on your back trying to stop it from falling :shock: onto your face!

Cheers guys, the tank is already off and in the skip, so no worries there. RIght will get a new filler neck etc ordered. I have to say it dig look a bit of a pig when I saw all the hoses on top.
Had a look on the wiki could not see anything about the hole sizes

Thanks again for the advise
