I went threw my entire binder of manuals and could not see any information on the need for lubrication of the gears in the injector pump of my Lx865. The rear of the injector pump looks allot like a power steering pump from a car. Should this casing have an oil in it? If so what type and how much? The "cap" does not a have a level indicator on it and is like an expanding rubber stopper.
