Leaking tank

[compass]

Hi Guys

Have a leak on the seam of my model D petrol tank.

What/who is the best approach to repair?

Thanks in advance for any help.

When I had this on Vespa Rally tank, I took the tank out, spent ages cleaning the insides of any petrol traces, then had it welded. I tested it so I was pretty certain the weld was good, then internally sealed the tank.

I didn’t trust just internally sealing the tank.
