FWIW I bumped this thread in my search for cheaper cents per mile transportation cost.

The US Department of Energy's Energy Information Admin has a cents per gallon for the spot and residential markets.

The latest market data as of Mar 17, 2008 for Indiana is 246.9 cents per gallon.

This might be useful for someone.

I'm thinkin about doing this to my 80. Any thoughts on putting the tanks under the body, where the spair tire sits on an 80? Pro/Cons.

I've got a 2F intake manifold if the configuration of the 3FE's plenum does not work.

If you are going to mount the tanks under the body, make sure to build some beefy skid plates to help protect them from any possible damage.

[Cruiser Jimmy]

Yeah, that's a major concern I have. I beefy protective undercarriage is going to be a most.


So how do you check the liquid in the tanks to monitor the level? What I mean is: are there any solutions to in-cab monitoring?

A proper vehicle tank will have provision for a float sender (similar to petrol tank sender).

G'day, The Blue & the Orange FJ40's both run duel fuel with tanks under slung at rear (quite common here).

The Blue one has no bash plate and does make occasional contact with the terrain but so far there hasn't been any huge explosions! The Orange one (mine) has a bash plate and had the tank lifted when a 2" body lift was fitted and thus far hasn't hit anything solid. So underneath is fine but better if you have a body lift.

My local Mechanic obtained & fitted the Fuel gauge to the tank - all I have to do is read the little lights - lots of green = you're go to go, Red = you're walking home. I know of a couple of 80 series running Duel fuel and they use the same gauge for both types.

One other thing if you go underneath, make sure the tank is heat shielded if the exhaust runs near it.

Cheers

any body know what the Californa law is on running Propane? I know there is a lot of natural gas buses here. Dose a propane car need to pass smog in CA?

Question for you Matty....

How do you fill you're tanks that are mounted under the rear? Do you have a high pressure fitting thats accessible?

What is the capacity of your tanks?

I'd love to switch to propane full time if I could work out the kinks........

Thanks for the info.

[Dudleyfj40]

I can answer your question for I have the same setup.


Mine is a 43# cylinder. I have to remove it to refuel.

Kind of a PITA but I think it is worth it.

If I didn't have my kids always with me I would put a larger one in the tub.

I am running a dual fuel setup.

You could make your own fill hose for the propane tank. Go to a local propane dealer that sells propane hoses and fitting and get two fittings that fit onto the liquid nozzle. Un-hook your primary hose and put the fill hose on and have your propane filled that way.

[Matty Awful]

It has a filler point in the rear quarter panel - no need to drop the tank. Best to recess the filler point so it doesn't get hit when wheeling & use a flexible hose between the filler point and the tank.

how do the valve seats hold up on the 2f and f engines with propane? I know on older domestic iron you have to swich to hardened seats.

I understand they have hardened seats factory - have had no problems with mine...
