22r Propane Conversion

[brimy311]

After doing a lot of research and not finding anything, I found a number for acme alternate fuels in Minnisota. I called and talked to Dave, he helped me though all the parts.

So for about $480 I got everything I needed minus a K&N filter and LP tanks.

PN# 149F-6-4 3/8” flare to ¼”NPT Male elbow 90 degre
PN# 48F-6-4 3/8” flare to ¼”NPT straight male connector

Prices vary based on length of fuel hose, type of fittings and how many forklift tank brackets you may buy. I was right around $480 shipped to my door. I bought a few extra fittings that I did not end up using. I also bought some other fittings from lowes.

This Cobra converter is only rated to up to 125 HP. So if you plan to run this on a turbo or a motor with more then 125HP, you would need to get a bigger converter. The 200m-2-2 carb/mix is plenty large enough to a very large array of motor sizes.

Fuel filter and vaccum fuel lock, This guy runs on vaccum pressure instead of a 12V+ wire. I like this idea for if my land cruiser was to get out of control and happen to die, it would lock off the fuel. With the 12v+ wire fuel lock, you often run the to a hot wire on your column and if you needed to get the fuel locked off, you would need to turn the key.

To figure out your high pressure hose length, you need to measure from where you plan to mount your tank to where you plan to mount your filter and converter. Be sure to get enough hose to also make a line from your tank to the bulk head.



I will get some pics of the install stuff soon.

[zebratoy]

Sweet Tech Have you installed it yet? If so hows she run

[brimy311]

I am in the process of installing it now. I am currently weeding out the 22r wiring to simplfy it all the way down to bare bones. I will get some install pics of what I have done.

[CrawlTech]

Post what wiring you get rid of too!
PICS!

I am trying to find an outlet for the mixer to toy carb adapter right now. But I might end up just making it.

I will get some progress pics soon.

Here is the bulkhead mounted through the floor.




lower part of bulkhead and Hydrostatic relief


here are the tanks mounts, they came powdercoated and came with mounting hardware.



I got the tanks from our local welding supply. They are aluminum. I got two tanks rented for a year for $41. So it costs me $20.50 a year to rent one tank. To buy them new was about $180 each. $16 for a fill. 33lb tanks.

here is the mount I made to mount the conveter and filter to the firewall.


I will post more pics soon. I am still working on getting the adapters to adapt the toy base carb to the mixer....but should have info on that soon.

What happened? We need a update dead threads dont help anyone

[66fj40x2]

Hello............... Is anyone out there?




Updates???

Thanks,
Mike

Sweet, I think you could make a dual fuel setup. Instead of using a mixer use a Impco spud in tube 2F SERIES part # 2F-275. Drill and tap it into the side of your carb or around the airhorn .There are 2 other interesting parts I found from impco in their catalog.
100 series fuel tube part # 100-29 is 2" #100-30 is 1.75"
130 series load block part
with electric fuel shutoffs on the gasoline and propane you can swith back and forth.

any progress?

He started wiring it today, I will give him a heads up on this post.

[brimy311]

I had it running the other night, I have an exhaust leak to fix and will get a video of it running once that is fixed. It idles around 560rpms, it revs extremely smooth.

[angeley]

dredging this up for an update?
Thanks

[brimy311]

It runs great! I have wheeled it a couple of times and really like it. The best part is that it always starts after sitting for months at time! I will try to get some updated pics and maybe a video of it running. But probably will not have it out of the barn for another week or so.

All the part numbers listed above were used, I did not have any variations and it runs awesome!

Sounds good have you computed your specific milage and power compared to gas?

His toy does not drive on the road.

[brimy311]

I have no idea of mileage, I would guess around 12mpg-ish. I can wheel two full days on one tank.
