Rated 4 out of 5 by from Direct fit I bought this around two months ago and i have to say, the tank itself is solid. It's a well made tank (made in Canada). The metal isnt thin by any means and can take a beating. I bought this for my 69 to upgrade from 20 gallons to 22 gallons and so far so good. I replaced my tank because it was rotted when i bought the car from old gas. Install itself was easy and took max 40 minutes from removing the old tank, scraping old sealer and installing new ones+gas tank. Two problems i ran into. The kit came in separate boxes and the box with the actual gas tank took a month to get here, It's not CJ's fault since they didnt ship it but was somewhat annoying 2nd problem was that the little o-ring gasket that goes on the sending unit was a bit big, it didnt seal correctly since it wasnt "pefectly" rounded around the unit so i had a gas leak and had the car run out of gas twice from the leak till i figured out what was happening. Had to remove the unit and find another gasket or seal it with something. Other than that annoying bit, the whole tank and unit worked fine and is well worth the price, maybe i just got unlucky and got the bad o-ring. I also suggest you undercoat the tank with some undercoating so it wont rust out This item is well worth the money as a kit, even more so if you do it on lets say a 67 to upgrade from a 16 gallon tank to a 22 gallon. You get better range for long road trips

Product Questions

I have a 70 fastback with a California fitted gas tank. (NOX system-the sticker on the speedometer is all I have left:) Will this work without having to purchase too many "extras" to make it work?

Asked by: momcat
Unsure what a "California fitted gas tank" is, but this part is universally able to fit in any 1970 Mustang. Depending on what your current tank's setup is, you might have to make a few mods, but most tanks are pretty universal.

Hi, can you please explain to me the difference between the 1970 fuel tank kit and the premium fuel tank kit. The pictures of the 2 fuel tank kit options appear to have different filler neck locations ?. I require a tank to fit a 1970 Fast Back Mustang.

Asked by: brock64
Both our standard fuel tank and premium fuel tank are the same shapes and sizes - the only difference is the materials used in constructing them. If listed to fit a 1970, it will be a perfect fit.

Fuel Tank Kit 1970 Video Transcript
By Bill Tumas: There's nothing worse than spending 60 bucks to fill up your tank, only to find gas dripping out from underneath your car. With the cost of fuel these days, there is no better time to replace that rusted, leaking tank. Today we're going to show you how to install a new tank using this '66 Mustang Convertible.

This is our standard fuel tank kit for the '65 through '68 Mustang. It includes the tank, sending unit with the correct brass float, mounting hardware, filler hose and the filler pipe gasket.

For this installation you will need a flat blade screwdriver, Philips screwdriver, hammer, 3/8-inch ratchet, 1/2-inch socket, 3/8-inch socket, 1/4-inch ratchet, 7/16-inch socket, 5/16-inch socket, short extension, wire cutters, pry bar, 3/8-inch open-end wrench, scraper, safety glasses and a lift or jack and jack stands.

As you can see, the tank in our '66 has a nice big dent in it. It's due for replacement. The first step is going to be to drain the fuel. There is a couple ways you can do this. Drain it either from your sending unit, or if the tank has a drain, you'll want to use that. The best way to drain it? Take your car for a drive. If it's not drivable, either one of these ways will work.

The last step before removing the fuel tank from above is to disconnect the sending unit. You're going to pull the sending unit wire off the stud and then you'll want to disconnect the hose. We have the original stock crimp-clamps, which are one-time only and so you'll want to cut that off. Keep your pan handy as you may still have a little fuel come out of it. Now, we are ready to move inside the trunk. After you drain the tank, you'll want to clear your trunk out and remove the bolts that are holding the tank in place. Now, we're going to loosen the two screws the hold the filler pipe seal to the tank and to the filler pipe.

Now, we're going to disconnect our filler pipe. To remove the filler pipe you have to take the gas cap off. There are four bolts in the front here and there is on the back that we have to get off first. You'll want to pull the filler hose off the tank by twisting the whole assembly. Twist the hose off the pipe and pull out your filler. You'll be reusing the filler tube with your new tank. We include a new hose and also a new gasket so you can throw both of those away. Now, we are ready to remove the tank from the car itself.

Even though the hardware is removed there is still some seal holding it in place. We're going to start with a pry bar and see if we can get it loose. If you have trouble getting it off with a pry bar, a jack underneath the car forcing it up will usually do the trick as well. We are going to be installing new sealant with the new tank and so we want to get the surface as clean as possible and scrape off the old excess sealant. Once you've finished cleaning the original sealant off the trunk you will probably have a couple areas that are bare metal. We recommend a coat of primer before you install the new tank. Once you're finished with the primer, it usually only takes about 5-10 minutes to set up and then we can get in to installing our tank. I will put some strip caulk around the outside edge before we install the new tank. This will replicate the OEM caulking. Make sure not to leave any gaps in the corners; you want to seal all the way around. Before the tank goes back in the car, you want to test your sending unit; whether it's the original or a new one, you will still need to test it before you put it on the car.

You will use your multimeter set on ohms to test your sending unit. You want to ground it anywhere on the chassis, push the positive to the stud. You should see somewhere between 70 and 80 ohms, which is empty. As the flow goes up, that number is going to decrease, getting roughly to 8-10 by the time the tank would be full. As you can see, our sending unit is working properly.

Once you have tested your sending unit and you know it's good, we are ready to install it. The first step is to install this ring. There is a groove that it goes in to. I will put the float in at an angle first and make sure that the stud is at the bottom and put the ring on. I get about _ turn by hand. I will use a hammer to push it on the rest of the way. If you are ever working with a sending unit that has fuel involved, you'll want to use a brass punch. Since everything is new here a flathead screwdriver and hammer will work fine. Now, we're ready to install our tank.

The tank is going to go in the same way the old one came out. Line up the holes and grab our new hardware. Right now, we're going to put the fuel filler hose on. It goes over the tank. Slide it down and put the clamp on, but we're not going to tighten it down just yet. Put another one over here. Now we will install the fuel filler pipe. The new gasket comes with it, so make sure that you put it on before you put the pipe in. Once you install the filler pipe, your hose plants in place and we will tighten them back down. Now, we will reinstall our gas cap. Line the gasket up with the holes. The last step is to connect the sending unit. Make sure that you grab a new hose clamp to replace the one we took off. Now, our installation is finished. Once you're finished with the install you'll want to put some fresh fuel in the tank and check everything for leaks before you take it for a test drive. Installation should only take you for about an hour so you'll be back on the road in no time.
