Good modern high strength threadseal
Good modern sealant, tested it on parallel chrome brass and stainless ( very inactive) positioning using hand pressure only. Needed warming to around 85c to get a set per the permabond website. 2 days after setting the nut broke getting it apart.
Compares well to the loctite I normally use (dont know about diesel/ ethanol) have not had to buy accelerator.
