How do you know if your vehicle needs a gas tank replacement? If it has a leak, smells of gasoline, or is corroded on the outside or has been sitting for so many years you don’t want to take any chances.
Well, first off if it’s an antique and barn find, you might want to replace it. When a car sits for a long period of time (newer cars) gas can go bad and clog up the pump, the filter, and the carburetor (older cars) or fuel injectors.
Fuel Tank Leak
If it’s been sitting awhile like my wagon had been, the seam that connects the top and bottom part of the tank together may have rusted through and then the fuel leaks/evaporates out of the car.
You will not see any leak on the ground usually unless it’s a good size hole and gasoline evaporates anyways. Just don’t light a match or smoke cigars/cigarettes near it. (It’s the fumes that burn not the actual fuel which is WHY you don’t smoke at the fuel pumps!)
The Fuel System Parts
If you’re going to replace the gas tank, you should consider buying all these parts at once. This way if they don’t get used, you can return them.
As always when looking up parts it’s year, make, model and engine size. If you don’t know you can ask the garage or have someone at the dealership run the VIN (vehicle identification number) and it will tell you the engine size.
You will need ….
- Gas tank with seal and ring
- Gas tank straps
- Sending unit/fuel pump
- fuel line clips (sending unit)
- 2 fuel hoses and clamps (gas neck)
- Gas neck
- fuel filter(s) with clips (some cars have more than one)
If that type of vehicle has more than one size tank in it, you will need to find the one you have. I went to the dealer to ask what to look for in order to find the information on it.
My Ford Taurus wagon (which is 25 years old) has a number stamped on the tank that they need in order to find the right size. I had to take that number to the dealer to have them look up the size.
Yes, you have to pay for shipping, but at least if you plan for the repair, you’ll have everything you need to do it before your scheduled repair.
Make sure you run the fuel down towards empty!
Ask How Long It Will Take
If you have things going on the day that the vehicle is due to be repaired, you may want to find out how long it’s going to take. I usually ask for worse case scenario because sometimes things don’t want to come off, something like a bolt breaks, or the person has a hard time getting the parts in or out.
If its going to be awhile and you have other scheduled things to do, then have someone pick you up at the garage and drop you off when the mechanics/technicians are done working on the car.
The mechanics/technicians at the garage will put fuel in and start the vehicle up and check for leaks. They may have to tighten some bolts if they seem loose or tighten the clamps on the hoses.
Once everything looks good and there are no leaks you’ll be able to pay them and leave.
If you bought the parts for someone to put into your car and there are ones that never got used, you should return them.
