In answer to Ruairidh's question I will try to explain my situation.
On my AD body the fuel tank goes through the "D" shaped hole in the firewall / bulkhead to be solidly mounted at the rear to the bottom lip of the dashboard with two bolts and nuts. On the front face of the fuel tank at the bottom there are two flanges that are to be retained to the bulkhead with a bolt and nut (I think). On my car there is a 1/4" gap between the flange and the bulkhead which if bolted tight would stress the tank and the bulkhead.
The tank is not insulated at all from vibration rubbing on the bulkhead opening and support lip which I don't particularly like at all. So I want to insulate the tank from rubbing and allow it some limited movement on the two new mounting studs I made with a soft rubber cushion on the stud between the bulkhead and the back of the tanks mounting flanges.
I would normally use a Nylok nut in this type of application to apply slight compression of the vibration cushion on the stud. The Nylok could be tightened or loosened as required and would stay in that state.
So I'm trying to establish what correct period lock nut would be used in this type of situation.
Cheers,
Stephen
