Is it safe to work on a gas tank?

The gas tank is located under your car and may need to get under your car. A good quality hydraulic jack and shaft holder is required. Never rely on jacks, always use axle supports to support the weight of the vehicle. I am a mechanic for over 20 years, I will not pass up the opportunity and neither should you. If you are going to open the gas tank, you will need to use it with caution. The gas is very flammable, prominent tools, wearing polyester clothing or a hand lamp are enough to ignite the fuel. Don’t be fooled by an empty container, it is equally dangerous as it is filled with highly flammable vapors. Check out my favorite tools on the Mechanical Tools page.

Locate the air pump

All cars from the mid-1990s had a gas fuel pump located inside the fuel tank. The fuel tank is located under the car. Many vehicles use an entry gate on the floor of the vehicle, usually in the trunk or under the floor of the rear seats. To remove the entrance gate cover, remove its latches, (usually three or four coarse-threaded screws). In addition, the cover can be fitted with a flexible gasket to prevent water and smoke from entering the cabin area. It is worth noting that on some rear-wheel drive vehicles, the fuel tank can fit in the ledge of the rear axle. In such setups, a double air pump and a sender (fuel gauge sensor) can be fitted. The second pump is used to balance the fuel between the two halves of the fuel tank. You now have access to the fuel pump housing, but before you can reach the gas pump you will need to remove the air lines and electrical connections. . I refer to that procedure under “Remove Airstrips”.

The straps are usually fastened to the chassis at one or both ends. Fuel tanks are made of plastic and are very sturdy, but playing too rough can break them.

Breaking bolts can ruin your day. Grinding and bare flame cannot be used to aid removal for obvious reasons.

Repeat for the second line, don’t worry you can’t mix them, the lines are different sizes. We’re not done yet, your fuel pump and the sender unit’s electrical connector need to be removed.

How to remove the fuel pump cover

With a gas tank on the vehicle or on the ground, removing the pump housing from the fuel tank is an identical process. First you will need to remove all dust and junk on top of the device. Compressed air works well, or with the aid of a clean paint brush. Allowing grit to enter the tank risks damaging the new fuel pump. The fuel pump housing is obviously where the fuel pump is located but is also a component known as the sender. The pump housing unit is held in place by a locking ring. There is a special tool to remove the lock ring, but a large flat screwdriver and rubber mallet are perfect for removing the lock ring.

The sender is connected to the fuel pump housing and is responsible for the gas level information. It uses a float on a dogleg rod that can rise and fall according to the gas level. Since the rod is connected to the housing, it cannot be lifted straight up, so the complete unit must be maneuvered 90 degrees when removed. Here you need a little patience, the disassembly can be a bit confusing but you will figure it out. Resist that temptation, bending the connecting rod will cause inaccurate fuel level readings.
