found a way to make a jeep idle

ditch the carb and vacume lines altogether and go PROPANE!!!! got a kit from Cary at 'gotpropane.com' worth every dime

hears some pics of the swap:

start with a crappy running non-idleing carb





start stripping all carb and vacume line crap off



start collecting all the devil equipment for the trash

mount the propane tank



begin running your hoses to the bed



otherside of the bulkhead attachment to run the hose up to the mixer



hose comming up to to the strainer, shut off silnoid and mixer, I mounted the mixer to a plate that I bolted to the mounts in the valve cover from the old air cleaner



ran the heater hose lines through the mixer and ran the line from the mixer to the carb plate



another look at the mixer and carb plate, and intake

gotta say, the kit from "Gotpropane.com" was kick ass. started at 10am on saterday and had it fired up running on propane by about 4pm. spent some more time cleaning it up and making it look better. runs like a fawking champ!!!

thanks Cary!!

any questions feel free to ask.

Cool, even a gravity fed fuel cell above the manifold and a ball-valve would be better than the damn stepper BBD carb.
How's the streetability?
What's the mpgs expected for a trail ride? More or less than the fuel tank?

well, dunno yet, just got it installed and its raining so I can't drive it to work yet. but drove it round the block a few times and so far, it seems to be very responsive to the throtle.

as far as mpgs for trail rides, I'm running a 7 gallon tank that 'should' last a full day of wheeling, but I don't have the first hand experince yet.

Mustard dog was running a 350 motor on his crusier and seemed to be able to last all weekend on 2 tanks.

kit was $900 plus $100 for the tank locally.

sadly it prolly isn't smog legal. I may try running by the referee just for shits and giggles but, I doubt that it'll pass.

bias ply Iroks are to soft to run on the street regually anyways

I'm not so sure on the smog legal part. I not only think it is, but it may also be able to qualify for alternative fuel/low emissions and get the special pass for the diamond lanes.

surveyboy,

Welcome to propane! I had the same problems you had with your carb but I went threw four before I changed to propane. The kit from gotpropane.com was ease to install it only took about 2 hours to finish and when it started for the first time it ran perfect. Wait until you are going up a hill an your side and have the same throttle response as if you were in your driveway! I installed the kit back in May and have wheeled all summer. It was one of the best mods I have done to the thing. It is like going from 31” tires to 37’s. Congratulations on the mod.

Oh and I am still planing on taking mine to get smoged but am waiting until I get my rear 4 link done so I can replace my exhaust and make sure my links do not hit it. I talked to my local smog guy and he said to bring it in. I hope it passes. If not it will be a trailer queen.

I am running a 28 gallon tank.It is a motor vehicle tank not a fork lift tank. I can only fill it 3/4 of the way full because of the pressure you can not fill it full. After about an hour drive to the trail both directions and wheeling from 5pm to 2am on Friday night, all day sat and half day Sunday I use just over a 1/4 of a tank.

Let me know what your smog guys say. It is much cleaner because it is a natural gas. I prob will not be able to smog mine for another month.

Do you also have the 258 I6?

Propane runs between 100 and 110 octane. I do not think it cut down on hp but that is my opinion.

Another converion to the Pane... I think it and my HEI were the best things I have ever done to my Jeep. I have more capacity in fuel with two propane tanks than I did with the stock gasoline tank. I run one till its out and then run the other. I can wheel two days at a crawl on one tank.

Okay I'm sold. Is there a tank you can mount under the vehicle in place of the stock gas tank so I dont loose my rear seat? Has to pull liquid not vapor right. So where can I find a tank for underneath for a YJ?

if you got creative, you could mount this tank down there, just have to build a false floor and hinge it so you can pull the tank out. and build a heck of a skid to protect it. my stock gas tank skid got beat to hell, I'd hate to have a propane tank get crunched. I thought about mounting this tank down there, and I think cary has his that way on a toyota truck.

I know shit about Pane but I was under the impression that it would actually increase HP per RPM but decrease the ability to reach a high RPM.
Numbers only for example;
Gasoline 150 HP at 4500 RPMs
Propane 150 HP at 2750 RPMs
The torque rating would follow this example.

Then again, I did say I don't know shit.

When I put my propane on I also added my t-case gears and now I have a lot of torque. At first every time I went out I broke both of my motor mounts and my tranny mount. I now have motor mounts from M.O.R.E. and they are the best I have not had any problems since.

Like I said in your post propane is safe but with the wheeling I do I would not trust a propane tank under my jeep. It is not a practical place for the tank unless you have some good protection.

Might be a bit OT but since you got rid of the carb and stuff would you like to sell the air filter housing? If so, please send me an email to frankegd att yahoo dot com with a qoute incl s/h to 73049

Thx
