I don't see that anyone has mentioned it but if your sender is faulty and the original brass float on it is not taking on gas use the old float with the new sender. I have personally replaced my senders 2 times because the plastic floats eventually take on gas. I finally got fed up with pulling my tank and bought a brass float for an old Chevy and haven't had any issues since.

and on the fuel sock....

there were a couple of us not long ago (3-4 months) that got one of them...omix 509263 15g... and the new fuel sock does not fit the down tube. the hole was to big. (hey I was going to the garage to get some beer so that worked out well....) don't tear up or toss the old one, we had to reuse it.

Ok, the tank is out

Not the sending unit or the ground, the float is full of gas.

The gas tank is not in the best of shape.

I looked and only find plastic replacements.

Anyone know of a direct steel factory type tank?

Rockauto.com shows several steel replacement tanks. I'm sure quadratec and 4wd have them as well. A brass float from an old mustang should be the correct brass float if you plan to just replace the float. A quick Google search shows this one for only $8. http://www.cjponyparts.com/product.a...FU8V7Aod-GoAUA

quadratec only shows plastic 15 gal tanks for 84, haven't gotten any further than that
They do show this

but state 15 Gallon Metal Fuel Tank for 1977 Jeep® CJ-5 & CJ-7, the vent tube is not right, but everthing else looks ok, I would have to measure the inlet, they state With 2-1/4" diameter inlet and 1-1/4" long filler neck

Looks like the filler is to large

Actually that picture is for a 76. The 77 had a filler neck about 6" long vs the 76 which is only about 1" long like the picture. Neither a 76 or 77 will work though since the filler necks are much bigger diameter than the 78+ tanks.

Found the right on on 4WD, Quadratec matched the price

It is crown, and unpainted, I hope it hold gas without leaking, will check and then power coat it black

No car nuts this weekend (well maybe for me) because I know this is a family get together weekend.

I have been lax in reporting Car Nut progress.

Last weekend we got together, and pulled the tank with three goals in mind. Get the fuel gauge to work (has not worked since I purchased the Jeep). Put a longer brake line in from the chassis to the rear axle (because of the lift) and install a hitch.

We put our minds (well theirs, not mine, I lost mine a long time ago) and it was decided it would be best to pull the tank, so we did.

Turns out there are five fuel lines that are connected to the tank; we labeled them all, pulled the tank and then the sending unit. It was found the sending unit works fine, but the float was full of fuel.

The tank is not in the best of shape, I have ordered another one. It is bare metal and I would like to powder coat it but am concerned about the heat needed to cure the powder. I called ; Crown Automotive Sales Co. Inc. (Headquarters) 83 Enterprise Drive Marshfield, MA 02050 781-319-3100

I may have to paint; the other thought is to try cleaning up the old original tank and powder coat it.

We got the skid plate and brackets cleaned and powder coated.

We also got started on some reinforcement brackets for the hitch.

Some clean up above the tank is also needed.

If none of the units turn you on, I'm in the process of doing a capacitive unit install.
So much better.

I had just responded to to another thread about gas gauges on CJs. I just pulled my tank and replaced the sending unit (For $40 why not put a new one in while you have the tank off, instead of trying to salvage a 35 yr old unit) Replaced all the Fuel/Vent hoses and made sure I had a very good ground to the sending unit. I took wire brush on my hand grinder and cleaned the tank and then painted with spray-on bed liner. Ive had good luck with this on other things, thought I would give it a try on the tank instead of painting. It looks good, we will see how it turns out.
