The fire extinguisher system consists of a front mounted Halon fire extinguisher, made by Phoenix. The Halon is routed by metal tubing to the engine compartment. There are two nozzle sprays in the engine compartment one on the passenger side, the other on the drivers side directed towards the engine (not pictured) .
The first picture shows the tube routing the halon to each of the carburator trumpets. These are mounted to the air filter boxes (and, in fact, the entire set up is completely reversible). As you can see from the rearward (front to the left) carburators, one can remove the air filter housing completely and the tubing remains inside the air filter housing. I forgot to take one of with the covers on, but the engine compartment from the top looks essentially stock.
The next two pictures shows a close-up of the tube routing and mounting in the air filter box. These tubes have holes in the botton, as shown in the next picture, showing the underside of the air box (note holes). The next picture is a close up of the hole (not very sophisticated, but it should work). The next post and picture shows the connection and routing of the tubing into the air filter boxes. The two air boxes are connected by the coupling and tubing shown. From the side, this tubing is visible and although it does not look original to the knowing eye, I think it looks OK visually in general.
The next picture shows the Halon fire extinguisher mounted to the front bracket. Not very pretty and I'm not sure what to do about that (??) other than live with it. The more important item in this picture is the 90 degree nozzle that allows the routing to the rear of the car of the cable to activate the extinguisher and the halon.
The next picture is a close up of the 90 degree nozzle. The next picture shows additional detail. The upper cable is the push button cable that is routed to the interior of the car. When one pushes the fire button in the car, the plunger brakes the seal and releases the Halon. The lower tubing carries the Halon once activated.
The next picture shows the push button inside the cockpit, that one would push to activate the Halon system. I hate the look of the thing and will eventually replace it with something a little more discrete (any ideas?).
I just realized that I also did not include pictures of a couple of additional items. In addition to the fire extinguisher system, the fuel pump that was on the car was replaced for a lower pressure one. Also, a fuel return line has been added to the car. A nipple was welded to the filler neck at the front of the car, and the appropriate tubing routed from the engine compartment to this location. Now when the fuel pump is activated, it runs continously, diverting excess fuel back to the fuel tank. Other changes include the aforementioned aluminum fuel tank and new fuel lines.
As mentioned in a previous post, all of these fire related improvements were the result of a sinking float that I had in one of the carburators which allowed fuel to continously flow from the top of the carburators all over the place. Thus, the top end carburator rebuild was also conducted.
I hope this is helpful and that I explained this well enough.
