Paul,
up until 1980, steel tanks of 20 litres capacity were fitted on 2CVs & Dyanes, later ones got the 25 litre plastic model.
The mounting points are identical, only change was the shape of the short rubber hose connecting the tank to the filler neck.

I did actually mention all this about tanks- metal and plastic - and tank volumes and sizes with regard to lowering it from between the chassis arms a few posts ago !!!
As is possible with a 4 wheel Lomax.

Ken
I presume (perhaps wrongly) that he wasn't using a forty year old petrol tank.

David

You mentioned plastic and steel tanks a few posts ago? The amount of useage this forum gets, I'm surprised I didn't see it. (434 members and the same old dozen or so who bother to write).

Don't use a hole saw, they require a pilot drill to locate and hold the saw is position. The drill extends some 30mm beyond the saw face so you will end up with a neat 6mm hole dead centre of the finished hole, unfortunately the hole is in the tank :twisted: Remrmber a hole saw needs torque to cut and using without a pilot will result is a disaster.
I would use a joiners tenon saw and progress very very slowly...checking all the time. You'll end up with a square hole but that can be covered up to give a pleasing finish.
best of luck Bill D
