Looks good. Hopefully that rust you mentioned isn't a real problem.

You asked for comments, so I'll give some. Forget about WVO conversions. If you want to burn waste oil, turn it into biodiesel. You will need new lines for either, but your pump and injectors will be much happier with that than with WVO, no matter how much you filter and heat it the latter.

My cars only get D2, but that's my choice.
