    As long as the fuel side is working, just make sure that the oil inlet is capped off so it doesn't suck air and cause damage to the internals. Disconnect the 4 wire harness from the oil side. Make sure you mix at 50:1 ratio. If you decide to replace it with a new VRO they (BRP) has recently had a price increase in their parts so have some nitro glycerin handy.

    That is totally up to you. If you choose to do it, mark your Oil tank at your current level. Mix TCW=3 oil to the gas at 50:1 ratio, connect the oil inlet line to the pump and with someone pumping the bulb attach the hose to the inlet fitting. Attach a ratchet clamp and keep pumping. Monitor the oil drop in the tank. If it drops they you should be good to go.
