Civic CNG Conversion

This post will cover the conversion of a 99 Honda Civic to run on CNG and Gasoline at optimal cost / fuel efficiency.

First consideration was where to put the CNG tank and how to secure it safely so that it is out of the way and also safe. I choose to put the tank in the back (obviously) so that it was out of the way - Now how does one get to the spare?

I hinged the tank and secured it with hitch pins and welded brackets out of angle iron - Here's a picture pre-paint:

Since the hinge was welded in, I fabricated a latch system out of angle iron and hitch pins to secure the other side to the body. Here are some more pictures of the installation.
