The cost of dropping a gas tank varies depending on the make and model of your vehicle, as well as whether you choose to do it yourself or have a professional mechanic do it for you.

If you opt to do it yourself, the main cost will be for the rental of a floor jack, which can range from $20 to $50 per day. You may also need to purchase new straps or other hardware to reattach the fuel tank, which can cost around $10.

If you choose to have a professional mechanic drop the gas tank for you, labor costs will vary depending on your location and the specific shop you use, but they can range from $50 to $100 per hour. In addition, you will need to pay for any parts that need to be replaced, such as a new fuel pump or fuel lines. The cost of these parts will depend on the make and model of your vehicle.

The typical gasoline pump costs between $100 and $200, depending on the car, and that is just for the component. If you have the misfortune of owning a car that needs the tank to be lowered, you may be looking at total parts and labor costs of $400 to $600.

That is, of course, if the lines stay intact and the repair proceeds well. Many times, the sending unit (a collection of tubes and pipes that lock onto the top of your gasoline tank and contain the pump itself) is severely corroded and rusted. This item is held in place by a locking ring.

If there are any problems with the transmitting device, the price might quickly rise. They usually rust out rather than go bad. As a result, they are not updated often, making them more costly and, at times, difficult to locate. On most models, replacing a sending unit along with the pump may push the total cost of the repair far above $1,000.

If the pressure lowers while viewing the findings, even while both valves are closed, this indicates a leak in the system.

What Other Issues Might I Face?

Rust is the most common problem faced while dealing with gasoline lines. Fuel lines are built of steel, which does not fare well in the weather. These lines rust and become exceedingly fragile. When this occurs, it is extremely simple to break a line merely by moving it, or even knocking a huge piece of rust off may reveal a small pinhole. If this occurs, you will be thrust into the dreadful realm of fuel line maintenance.

If you’re fortunate, you may be able to get away with merely replacing the leaking line. However, if the rust accumulation is severe enough, you may have to replace all of the lines. This might cause the labor time to exceed a day. It may also cause the price to rise beyond $1,000.
