Fuel tank leak


Recommended Posts

I discovered that my fuel tank is leaking.  The leak is cracked at the toe of the weld attaching one of the angle iron mounting tabs.  I am thinking about removing the tank to have it welded.  Has anyone done this?  Is there anything I should know?  How much does it weigh, can two people man-handle a mostly empty tank out of the drivers side?

Mine does not look like it can be lowered.  It is setting in an angle iron frame with a couple of bars below the tank.  Everything appears to be welded.

.You can just weld it in place. Disconnect all batteries and place welder ground close to where it needs repaired. Open fuel cap and run a car exhaust to it running with a semi enclosed hose. After about 30 minutes it should be pretty warm and you can weld on it. Talk to a few welding shops in your area and I am sure you can find one that knows how to do it this way.

If you are scared to have it welded on. Another solution is to use an epoxy steel product by JB Weld where you clean the area and just press it in place even with a leaking area.

I had a leaking fuel tank on another coach and tried a couple different epoxy type repairs with no luck. They stopped it for awhile but in the end it started leaking again (the last one on the day the new owner came to pick up the coach). I was able to find a shop that would weld it but I had to remove the tank and take it to him.

If you are in a rural area…farming, I would find a repair shop and see if they would weld on it in place assuming you can get a rod to the crack. After leaning the coach so no diesel is on that side and gassing it like Ken suggested, I would weld on it in place.

Here is a site that you can go to, to calculate the approximate weight of the tank.https://www.chapelsteel.com/weight-steel-plate.html  Many fuel tanks where/are weld repaired in the Military.  Also construction equipment repair Co.'s do it all the time.  Ask around at TRUCK repair shops.  I would not patch it.
