If you're having trouble with your 1982 Corvette, it could be time to replace the fuel pump. This is located in the fuel tank, which will need to be removed to change the pump. The fuel will need to be drained, the fuel hoses and electrical connections removed, and the fuel tank straps unbolted. You'll also need to ensure the system has a minimum of 13 to 15 PSI of fuel pressure. If it doesn't, it's starving for fuel and won't run properly.

What You'll Learn
The fuel pump is located in the fuel tank
The fuel pump is an essential component of the Corvette's fuel system, which needs a minimum of 13 to 15 PSI of fuel pressure to run correctly. If the fuel pressure drops too low, the engine will not run properly and may stall. Old fuel lines and hoses can also cause issues, as they may become kinked, dented, or collapsed over time, restricting fuel flow.

Drain the fuel and remove the fuel hoses
To drain the fuel and remove the fuel hoses from a 1982 Corvette, you will need to follow these steps:
First, make sure to pinch off the hose about a foot back to prevent gravity from emptying your gas tank. Old fuel lines and hoses may cause restrictions due to kinks and/or dents, so be careful when handling them.
Next, locate the gas filter, which is on the frame rail behind the front right tire. It is held in place by a bolt and bracket. Loosen the hose clamps and then remove the gas filter.
Once the gas filter is removed, you can drain the fuel from the tank. Place a container under the drain plug and remove the plug to allow the fuel to drain.
Finally, you can remove the fuel hoses. Start by disconnecting the hoses from the fuel pump and fuel tank. Be sure to also disconnect any electrical connections to the fuel tank. With the hoses removed, you can now access the fuel pump for replacement.
Remember to work in a well-ventilated area and take the necessary safety precautions when working with fuel.

Remove the electrical connection to the tank
To remove the electrical connection to the tank, you must first drain the fuel from the tank. You can do this by pinching off the hose about a foot back to prevent gravity from emptying your gas tank. Next, remove the fuel hoses and the electrical connection to the tank. Be sure to unbolt the two fuel tank straps and lower the tank down.
If you are experiencing issues with your fuel pump, it may be due to debris stuck in the regulator. To clear this, with the engine running, try lifting up on the pressure regulator tab. Insert a small flat-blade screwdriver into the hole and lift up on the tab, then let it snap back down to re-seat the regulator. The engine will stall, but this may clear out any debris stuck in the regulator. It will flush back to the gas tank through the return line. Once the debris is cleared, the regulator should run at a consistent pressure rate.
If you are still experiencing issues with your fuel pump, it may be due to old fuel lines and hoses. Over time, these can cause restrictions due to kinks and/or dents, and old rubber lines may have collapsed inner portions. To replace the fuel pump, you will need to remove the fuel tank. This can be done by draining the fuel, removing the fuel hoses and electrical connection, and then unbolting the fuel tank straps.
It is important to note that the fuel pump is located in the fuel tank of a 1982 Corvette. The process of replacing it may take around 1.5 hours.

Unbolt the fuel tank straps
To replace the fuel pump on a 1982 Corvette, you will need to unbolt the fuel tank straps. The fuel pump is located in the fuel tank, so the tank will need to be removed to access the pump. Before you begin, make sure you drain the fuel and remove the fuel hoses and electrical connections to the tank.
To unbolt the fuel tank straps, you will need to locate them on the underside of the vehicle. There should be two straps, one on each side of the fuel tank. Use a socket wrench or a ratchet and socket to loosen and remove the bolts that secure the straps to the vehicle's frame. Once the bolts are removed, you can carefully lower the fuel tank down and access the fuel pump.
It is important to note that you should always take proper safety precautions when working on your vehicle, especially when dealing with fuel. Make sure you are in a well-ventilated area and that there are no open flames or sparks nearby. Wear safety goggles and gloves to protect your eyes and hands.
Additionally, before you begin the replacement process, it is recommended to pinch off the fuel hose about a foot back to prevent gravity from emptying your gas tank. Old fuel lines and hoses may also cause restrictions due to kinks and/or dents, so be sure to inspect them before proceeding.
