Changing a Kalahari tank

[Bubb]

I had them on a type filler on my ST ( after the original bmw filler broke) if I remember correctly the whole lot just screws in, and there is a small grub screw inside to hold it. Don’t drop the Allen key into the tank!
Can’t help re the petrol taps I m afraid.

PS, the paint looks great.

Think those petrol fillers just push in. There should be a hard felt washer between the tap and the tank.

Thanks for that, does that mean between the union bolt, that the tap screws into and the tap itself? That seems to make sense
