I need to rebuild fuel pump for my 70 hp Evinrude (1990). It had the VRO dissconnected and plugged years ago. I am told there is no rebuild kit for the fuel pump. There is a kit for the VRO (part # 18-7821) Will this rebuild the fuel pump or oil injection? I really don't want to spend $160 at the dealer for a non-VRO fuel pump. Any ideas?
