"reconditioned" gas tank

[drlogistics]

Next up on my to-do list is my gas tank. It hasn't been used in a long time. It is full of rust dust. I've been running the truck off a plastic 5 gallon tank mounted to the driver side step. Not exactly DOT approved. And it just plain looks wrong. The original tank looks like it would hold gas but I didn't want to spend the money to have it professionally reconditioned. Actually, my wife didn't want me to spend the money to have it done. So, I decided to hide a new tank inside the old one. I came across several brand new gas tanks that were supposed to be destroyed by the company that tested them. Lucky for me, they left a few intact. Some quick dumpster diving yielded some great treasure. I found a tank that fits inside the m211 tank. So today I started the project. In true Gunfreak fashion, the following statements correspond to the pictures.

1. The old tank ready to be cut.

2. The new tank.

3. New and old side view.

4. Top cut with an angle grinder. I do not claim to be a master fabricator so I don't need to hear about how the cut isn't straight. My truck will never be a museum piece.

5. The top removed exposing the baffles.

6. This is the underside of the top piece. Obviously it is in much better shape than the rest of the tank.

I will be doing some more work on it tomorrow. Hopefully including fabricating the filler neck and the some kind of system to keep the new tank stationary inside the old one.

The desecration of an original tank

Could use some expanding foam to keep the new tank from moving around in the old tank.

Thanks FireFighter. Do you think the spray foam will hold up to the vibration caused by driving?

No Idea

It should I have used it for many things.

any ol closed cell foam should do the trick, though i dont think you will find anything that is going to like gas! so make sure their is no chance of laks during filling or the vent.

Whats the capacity of that new tank? Looks a tad small, though i suppose if you go for short rides its not too bad LOL

We clean tanks daily; boats, farm, construction, military, etc. Gasoline, diesel, fuel oil, any of the fuels and this is what keeps us busy, dirty fuel tanks. In this case a good fuel filter with proper care could have save the original tank from being as it is now. Oh well, "to each his own". As for pouring a foam around the tank. The chemical reaction when it 'kicks' will reshape that tank.

After you cut the tank open you should sandblast it and weld up pin holes then weld the top back on and not worry about fitting another tank inside it. To me it seems less work to do what I just typed than to try and make that tank work....but that's just my way of thinking. Your truck do as you want.
