In the second picture above the curled hose is your Carburator Pumping diaphram Looks like it could be bad which could cause some of the problems of starving for gas.

I'm convinced your issue is that all the crud in your tank is plugging your fuel filter and starving the motor. You're on the right track by cleaning up your fuel system and replacing the tank.

And BTW, chicks with CJs are HOT!

My new tank kit came in yesterday!! Yay! I know I won't have time to play, this weekend, though. And next weekend is the Carolina Cup! So... I guess now, the hard part will be finding TIME!
Thanks Guys!!

I put the new 21 gallon tank in this weekend! I also put on a new fuel pump, fuel filter, hoses, filler neck, filler hose, vent hose, and the extensions for my skid plate.
It still won't run! Looks like the carb is messed up! Now, I'm lost again. The carb has motor craft on it, but it also has a sticker that says it was re-man'd by Holley. So, how do I figure out what kind of rebuild kit to buy? Or should I just buy a new carb?

Should I just buy a new carburetor? Everything that I'm reading says to stay with Motor Craft...

I wouldn't buy a new carb yet. There should be a tag on that carb with a series of numbers and letters. Normally like this xxxx - xxxx, on an aluminum tag bolted to the top of the carb. Your's may be on that sticker on the side. Copy them down and go get a rebuild kit. Really easy to rebuild these motorcraft carbs. As said before, it looks like your accelerator pump has some issues, a new diaphram will come in the kit.

There isn't a tag on the carb at all! Just the Holley re-man sticker... I did some looking though and went ahead & ordered a rebuild kit for a Motorcraft 2100. I hope that will work! :-/ anyway, it should be here Friday, so I guess I know what I'll be doing this weekend! I REALLY hope to get this thing running by Tuesday!

I've also looked everywhere I can think for the accelerator pump diaphragm thing... I hope it comes with the re-build kit because I can't find it anywhere! I also got a new PCV valve, but I'm having a hard time finding the elbow & hose?! Any ideas?
Oh! One more thing... I got a new oil filler cap. Do I need to put a hose on it going to the air cleaner? The old hose is in really bad shape.

on the 2100 and 2150 kits there use to be 2 kits one with the power valve one with out; I do not know if they still do that but the kit should have the accelerator pump diaphragm in the kit - my PVC valve just had a hose on it to the carb - the oil cap it does not hurt it to go to the air cleaner

you also might like to check the throttle cable, in the forth pic it looks like the plastic sleeves are broken and could be running into each other when you push the pedal. I doubt thats the cause of the current problem but something to consider.

I ordered a new cable today... It wasn't on hand though. Quadratec said it may be a week or 2...

Okay, so.... I can't find a rubber grommet for the PCV valve. Guess I need to order one! The accelerator cable did come in! (I LOVE QUADRATEC!) The Carb. is off the jeep and soaking tonight. Tomorrow I will try to get it cleaned up and put back together!
Now, the current show stopper....
My husband and I have both been trying to work on the brakes. The rear brakes, we replaced all the little pieces and parts, put new wheel cylinders (?) on, and new shoes. Rear brakes are back together! FRONT BRAKES- I bought the SSBC 12" brake conversion kit.... I also bought new wheel bearings, seals, lock rings, etc. But, I can't get the outer lock ring and nut on. There's room for the lock ring, but then there's no thread to even start the nut! So, here's my question: The seal (on the back side of the hub)- should it be flush with the back of the hub? That's the only place I can think that we may be able to gain space for the front side. Am I crazy here? What am I doing wrong?

So, I'm not crazy... After I re-seated the seal, it all went together beautifully! I hope to drill out the bracket for the brake line tonight & have the tires back on before bedtime.

Have you found your PCV valve location yet? It's important to have the hose on the oil filler cap connected to the air cleaner. It creates a good flow for the pcv valve to work properly.
