Re: Dump the VRO and mix
txswinner,<br /><br />By "91" the oil injection systems were very reliable. I would not replace the pump, as long as you know it works. See above.<br /><br />It might not be a bad idea to clean out the tank though. Just dump the old oil. Refill and reprime. Run 50:1 until you VERIFY you are using oil from the tank.<br /><br />Enjoy the freedom of not having to pre-mix.
