You mean the Petrol Tank balance pipe, which I believe to be plated copper pipe, so you should be able to clean up the fitting after removal with some heat and have it re-silver soldered.
If you were going down the route of buying a new pipe (from Draganfly?), then I would lean towards the 3 1/2" centre one as the pipe has a little 'give' in it to allow making up to the tank fittings. HTH

Thanks for the reply ,
Pipe is ok but rose at the end is not seating ,
Tried both ways round and polished with wet and dry but to no avail
I think I'll try as you say the 3 1/2 can't quite understand why neither of the two measurements are right ?  That's Pattern parts
Thanks again

As a quick test, why not wrap the end of the fitting with some PTFE tape to see if it seals better?
