It`s on special at the moment and that means fantastic value for money. They have many informative videos on their site with a great "talking" presentation. Their guide is about 100 pages long with many diagrams and it`s very detailed in the water fuel conversion process.

Description: Half Water Half Gas is the new kid on the block when it comes to water fuel conversion and it`s truly proving itself. Having just finished our test trials on 2 different vehicles we can say that this is a fine product. Their site is one of the best and is heavily detailed with many videos you won`t find anywhere else. Their e-book comes with three freebies on various automotive-related subjects, they are actually useful! Their water car instructions are aimed at mid-range users and would appeal to the broadest range of "backyard mechanics" in our opinion. This product has risen in the ranks and is one of the best sellers right now! Very highly recommended.

Great for the user who wants to build a more advanced water fuel system.
