Hi there hope someone can help
I've just bought a tank seat unit for my 1973 Cota 247 that has the original fibreglass tank and not the separate aluminium tank. I got it to replace a leaking Ali tank and cover. Unfortunately, the 12mm petrol tap from the ali tank does not fit the fibreglass tank. The tap boss on the fibreglass tank appears to have a 16mm metric thread on it. Unfortunately, the tank came without a petrol tap and none of the usual firms can supply a 16mm petrol tap.
Any ideas on what to do please?
