Ken, we use a oil pressure switch that turns on with about 5 psi of oil to run the engine hourmeter on the rental machines at Empire. If there is no oil galley plugs that the switch can go into, we splice into the R terminal wire for the alternator. If you are going to run the pump that is. I havent run into that much with the cats, but what kind of incline are we talking about. Anyway, I think that a low pressure pump would work, you dont have to worry too much about overpressurizing the system. Also you can prime the filters without that stupid little priming pump that never works. I dont know if that machine has an orificed connector on the outlet for the fuel system. For example, we have had a problem with 950G jerky hydraulic controls because we have too much flow going to the pilot valve, so we remove a full flow connector and install an orificed connector. It works fine then after. Let us know what happens. Also one other thing that we have run into is some people make fuel lines out of the aeroquip fittings, where you screw one piece into the end of the hose, and the hose peels up inside and creates a flapper which can close off the line when in a vacuum.
