Depending on how much space you have, you could try out something from Fire Bottle. I don't have any experience with it, just seen it before.

I had a Fire Bottle system in 2 Formula racecars I had. It is a very simple system. It starts out with a Fire Extinguisher filled with Halon. The Fire Extinguisher is mounted remote from the engine. In the formula cars I had it was between my legs! At the end of the outlet of the Fire Extinguisher are 2 copper tubes. One ran to the engine and on to the driver.
To activate the Fire Extinguisher all you had to do was pull a safety pin before the race and if there was a fire during the race you just pulled a knob on the dash that ran to the Fire Extinguisher via a cable.
I would think you could plum the copper tube to any car/truck just like a Formula racecar.

Dave - I have to ask why you want to do this. Fires in the engine can occur with every make and model of vehicle but no more with a landie than any other vehicle. If you are experiencing too much heat in the engine bay, I would look at ways to alleviate that heat build up as opposed to putting in this type of system. If a fire does occur, the aluminum block will be toast from the heat before the system can even do it's job.
Although I think this type of system is pretty cool, though!
*edit - I stand corrected. Certain years the 110's were prone to engine bay fires due to the routing of oil lines.

From my understanding, not only the 110's, but all of the 90's with the 3.9/4.0 engines with the oil cooler lines. I'm sure this will apply to the Disco's of the same era. The problem was the hoses proximatey to the exhaust manifold. The solution is to replace them every 10 years or have a replacement set w/ braided hoses made.

How ironic...
Just saw something in a LR Mag just yesterday. I believe it is called the Flexifire something or other. It is fully automatic and originally used on rally cars on the Paris-Dakar. As a matter of fact, very interested in this myself and would love to hear from anyone that has any more information.

Something else to consider is a fire bottle like they use in boat engine compartments. It would be highly advisable to rig up an experiment though to find out how high 'normal' under hood temperatures can get (you know under low speed, heavy load, high outside temperature conditions) before installing any type of automatic system, since they all are tripped by temperature exceeding a certain threshold. I'd be pretty concerned that 'normal' under hood temps might be higher than the trigger threshold though for boat style fire bottles like Fire Boy (175 degree trigger) or Sea Fire though (didn't see a trigger temp listed on the site), leading to discharge when not needed and an expensive paperweight.
Because these systems are designed for essentially sealed spaces, it would also be advisable to increase the standard capacity/per cubic feet of area to be covered to compensate for agent loss.
I also meant to include a link to the Fire Trace brochure for Commercial construction equipment. Like Sea Fire, I can't find a spec readily on discharge temperature, but I would think it would be higher than the FireBoy systems. Another nice feature of the Fire Trace would be the ability to cover multiple areas with one system (think under seat boxes as well as under hood) because of the design. Neat stuff..

In the race car stuff you can buy either a kit or the bits individually. The nozzles are machined aluminum and have male -4AN fittings on them. Those I've worked with and installed used dead soft aluminum 1/4" tube, which is available from any quality house plumbing shop. Can likely use copper too, just haven't seen it done. It's pretty easy to flare, can even use a std. SAE 45* flare tool when using the aluminum tube as it will 're-flare' itself when you tighten the tube nut & tube sleeve onto the 37* fitting. That's not normally considered good practice, but in this particular application it is OK.
