, CONT.

NOTE:

Use only clean engine oil on the pipe

threads. Teflon tape or pipe sealant is not

recommended as it might loosen and cause

blockage of the small oil feed orifice result-

ing in possible supercharger failure.

NOTE:

Ensure that the hose does not have any

dips or kinks in the routing.

Supercharger failure may be the result of a

restricted drain path.

*Applies to "engine oil-fed" units only. V-3 applications

skip these steps.
