I have no idea what happened to your lengthy post. It doesn't seem to be around anywhere. My suggestion is to retype the whole thing again, then copy and save it to a word document just in case it gets lost again somehow.
Your post was tagged as moderated. The system seems to do that with long posts or stuff with lots of numbers, etc. in them.
I've released it, so no need to repost.
I've also commented to Administrator about that. Seems like more and more posts need to be approved by a moderator.
Welcome to TheDieselStop. And thanks for the informative post. :thumbsup:
