Replacing a Chevrolet Fuel Tank
A lot of things can go wrong with your Chevy, from missing bolts and torn bushings to loose belts and busted engine components. The Chevrolet fuel tank is probably the last thing on your mind. But this, too, can break or get damaged. It can be punctured and may leak. It may also have defective or damaged seams or may have loose hardware somewhere. There are tank repair kits, but these don't always work. If you have to replace the fuel tank, we can help you figure it out. Here's a quick guide:
Required skill level: Intermediate
Needed tools and materials
- Replacement fuel tank
- Wrenches, sockets, and other basic hand tools
- Fuel line
- Hose clamps
- Gas storage container
Note: Have a fire extinguisher on hand since gas is highly combustible.
Draining the fuel tank
Empty the fuel tank. If the fuel tank has a drain cock, you have to ease the valve to drain the fuel. If it doesn't have a drain cock, you have to disconnect one of the fuel lines. The rubber hose that leaves the tank at the lowest part will drain it. This can be linked to a fuel pump, fuel filter, or fuel line running to the front of the vehicle. You have to unlock the clamp at the end of the line that runs to the gas tank. The hose must be pulled off so that the gas can be poured into a receptacle. This should be stored properly. This can be used to fill in the new tank.
Disconnecting the fuel lines
Remove the fuel lines that are linked to the fuel tank. You'll be pulling out more than just one line and will have to locate the fuel supply line that exits the tank at the lowest point and runs towards the fuel pump or engine, the large fill tube from the gas fill entry point, and the vent line that lets pressure escape.
Note: Take a picture of the setup so that you can reassemble them later.
Dropping the rear suspension (not a requirement to all vehicles)
Note: If the tank can be pulled out with the rear suspension in place, you can skip this step. You have to check the setup to find out if this needs to be done.
Detach the rear shock absorbers' bottom fitting. Once this is disconnected, you have to pull down the rear suspension and take it away from the dangling shocks. Use a jack to hold the rear suspension beam or drive assembly at the center in place. You also have to undo the lower shock mount bolts. To prevent damage on the rear brake lines, disengage them. After this, you may now release the large nuts linking the rear beam or drive assembly to the frame. Use the jack to lower the assembly to the ground.
Removing the fuel tank fuel tank and installing the new one
Unhook the metal straps that secure the fuel tank. To do this, you have to loosen the nuts located at the straps' end. As you pull them down and unhinge them from the other end, you can now remove the old fuel tank and put in the new one. Just reverse the earlier steps to install the new tank.
