Now we have to install the firing mechanism in a location that will be easily accessible to the driver. The easiest place to do so on most vehicles is the dash. But the leg braces on the seat will work as well. To do this, we unscrewed the firing mechanism and drilled a 3/8 inch hole into the dash.
This is a perfect location for the firing pin. Notice how we have taken a zip tie and wrapped it in duct tape. This allows the driver to pull the safety pin and the firing mechanism easily.
Now we need to install the rear and front extinguisher port. We'll use a splitter that will push the chemical to the driver's seat and the rear of the car. Here's everything that we will need. You might notice that we have two different types of splitters. The bottom splitter and fitting is a compression fitting. The top fitting is a flare-style fitting. Both have advantages, the compression fitting doesn't require you to flange the 1/4-inch pipe. As you tighten the nut on the pipe, the compression ring will seal to the extinguisher port. Whereas with the flare-style fitting, you'll have to flange the pipe, but it will seal extremely well to the port and splitter.
Next, we'll measure out how much line we'll need. Then we'll cut and flare it.
Once measured, we'll use a small pipe cutter to make a clean cut through the 1/4-inch pipe.
With the pipe cut, we need to bend it to keep it flush against the floorpan. We just follow the bender here and put the 90-degree bend in it that we need.
The bends came out perfect, and now we just need to drill through the rear sheetmetal to the fuel cell and then hook up the splitter.
We found a spot that will work perfect for the port. Once we drill through the sheetmetal, we'll measure our line again, cut and angle it, and then attach our flare fitting.
We need to put our nut and the flare in the right order so that we can flange our extinguisher line.
This tool will allow us to flare the pipe without damaging it.
Make certain that the flare tool is centered in the pipe and then tighten it up. As it tightens, it will expand the pipe.
The bend and the flare came out great. Now all we have to do is attach the pipe and then secure it to the sheetmetal.
Here's what the port looks like from the bottom of the fuel cell. It's pointed directly at the fuel cell in case the worst happens.
Finally, we'll take several small securing brackets and rivet them to the sheetmetal every 5 inches or so. This will ensure that the line doesn't break or move during an accident.
