       I've got the oil = injection location in the front cover to block, so maybe I'll just put = a fitting in a cover plate and return it there. 

      Last night I had a quick look at this, = and I feel that there is almost no vertical drop between the RD-1A = outlets and the injection oil pump fitting. As oil likes to flow down = hill, this might not be to succesful. Routing is the other concern. I = wouldn't want to route the line too close to the exhaust to avoid = picking up any heat in the oil.

      That was the original = plane.  Of course I am going to install a hose to the oil pan = drain bolt anyway, just for oil change purposes.   =

 I thinking about doing this too.
