Oil cooler lines/hoses 1983 454

[blakeduren]

New info parts numbers to add:
If you buy Hayden 112 it is Gates brand hose.
It is best to use a 18-20 mm sized fuel injection clamp...my 16-18 mm just barely fit.

The two hoses on my 83 are almost completely identical except for a tiny bend in the long metal tube near the oil filter adaptor.

The oil filter adaptor housing uses a gasket and an o-ring between it and the engine block. Some auto parts list a Dorman kit for this but it’s wrong. The proper gm part for the gasket and o ring is 88893990.
