I just got done changing the ether cylinder on my deuce and bleeding the system after I ran it out of fuel last week end. Turns out the cylinder was empty. I tried a few times to start it when the temp got below 20 degrees and it started just by cranking and giving some of the go pedal. I wonder how well it will start with a cylinder with ether in it? I also was going to drain my fuel tank since it was nearly empty to clean out any residue in the tank. I put in a 1/2 inch socket wrench and when I tried to remove the plug the thing exploded on me. It was still holding so I will work on replacing the plug when it is warmer out.

I tried getting the plug outa mine once and with a 4ft bar it wouldnt move. I was afraid if it did I might rip the bottom of the tank off so I just quit.

It takes a 9/16 allen wrench to turn the tank drain plug....

Above freezing mine starts right up, below freezing it takes more cranking but if I hit the ether switch it starts instantly, if its zero or below I hit the ether one or two more times while it's running to smooth it out. Best investment I made.

Mine was the same 1/2 inch square opening used on the diffs, trans, and transfer. Someone must have changed yours or mine. The 1/2 inch socket wrench fit tight until it exploded. It would make sense to have it the same as the rest of the truck. If is a cast piece so when it gets warmer I will drill out the middle then knock the rest of it out with a punch. It seems to be brittle and should chip out just fine. Then I will need to get a plug to fill it. I fugured it is probably the same plugs used on the diffs. I will verify and order a new one from somewhere. I will probably get stuck calling Memphis for it unless anyone here has a junk trans, tranfer case, or diffs.

Hey Chuck
I'm sure my plugs on stuff are the 1/2" square drive too. That being so, sure seems like they are National Pipe Thread. Without looking, I can't guess if its half or three quarters of an inch pipe plug. That is where I would be looking - check a differential plug for comparison. My bet is, they are all the same.

Sounds like that is one of those simple, innocent, jobs, that turns into a BIG job - like you end up having to pull the tank, so you can work on it properly. You sure don't want that thing to be seeping.

By the way - its -40f out. I already know, mine won't start. But I just got an engine coolant heater from Ebay, and as soon as I can make room in the shop, I will get it iinstallled. When its cold for real, you want to put heat on them. It save a lot of wear & tear!

Interesting, I made the assumption based on that I have 4 different tanks, 2 deuce and 2 M52A2 fuel tanks, all having the 9/16" allen plug....
