Diesel Fuel Tank Repair

If you are lucky, you have a diesel vehicle that has lasted a long time and is still in great condition. If you have noticed that you are losing fuel or that you are running on empty much more often than you should be, you may find that you have a leak or hole in your diesel fuel tank. Luckily, there are many different options in front of you that will allow you to try to save the fuel tank if you would like. Many times the cost of repairing the fuel tank is much more affordable than buying and installing a new one.

If you are sure that you have a leak in your diesel fuel tank you should consider repairing it before you just replace it. If you are handy at all you may be able to make the repairs to your gas tank for very little money. If you repair the tank you may have to spend hundreds of dollars. It is worth the attempt to fix it before you put out more money than you have to.

It doesn't matter what sort of diesel fuel tank that you may have, plastic or metal, there are repair options available. You need to be sure of which material the tank is made from before you start. If you have a plastic diesel fuel tank you can use a poly weld stick, which will simply melt into the hole and will fix your problem with relative ease. If you are working with a metal diesel fuel tank you can also weld this. Of course, it is important to know how to weld safely before you attempt welding for the first time, especially because if you over heat you could damage the tank further and if you under heat the surface it will not fix the leak.

There are some people who will tell you that you can use simple products such as hot glue to fix a diesel fuel tank on a car or boat, but this is not true and it is not even a good idea. Usually the hot glue will not even stick to the surface of the tank, but it can also heat up and end up on the inside of the fuel tank and then in your engine as a result.

If you are unsure of how to repair your diesel fuel tank it doesn't mean that you have to buy a new tank. What this means is that you just need to get some outside help. There are a lot of different processes that have been patented for repairing fuel tanks and you can bring or send your fuel tank to one of these providers that will allow you to get your fuel tank repaired. The cost of repair from these companies usually costs anywhere from $150 to $400 depending on the damage as well as what kind of diesel fuel tank that you have on hand.

If your diesel fuel tank has become so old and worn that it simply is crushed with a bit of pressure or the metal simply flakes away, it is probably a better idea to purchase a new one than to try to salvage the tank. You get to a point where you are just asking for more problems by repairing the tank. You will need to use your best judgment when choosing to repair a diesel fuel tank, considering how much money you will be saving by repairing as opposed to buying a new tank.

  1. Hi. I have an old sailboat that converted from a gasoline engine to a diesel engine. Thus the tank is made out of galvanized steel. It has developed a leak at a seal and I would like to repair it. I would like to simply fiberglass the area, which seems to take the fiberglass. Some of my friends say that the diesel will dissolve the reisin. Is that true? Or can I repair the tank this way?

  2. I have a 40 gallon steel diesel tank that has a small crack about a 1/4 of an inch long. The truck was recently picked up with a hydraulic lift that I suspect put pressure on the tank and cracked the weld. The crack is located on the bottom edge of the tank pretty easy to get to. Will the tank be required to be emptied or filled to repair the crack by welding. I already tried fuel tank putty. Held for a while but it is leaking again. Any ideas would be great but I think it will need to be welded.
