* The proper and careful installation of the silver fuel injector adapter into the cylinder head is important. Follow the most recent SDS instructions. Use only the referenced high temperature blue Loctite 246. Hand tight, then 1 1/2 turns. There are older instructions out there that reference 60 inch pounds torque which is no longer a desired tightening method and may not be enough to hold the adapters in. | * The proper and careful installation of the silver fuel injector adapter into the cylinder head is important.
