Sediment bowl and tank

[Joeandmack]

Afternoon everyone,

It might be 2058 before my 1958 Cub gets to the point where I really would want it to be, but I’m chipping away at it one piece at a time. Being able to work outside now with the weather in Central New Hampshire makes it more enjoyable too. It appears the previous owner either soldered or welded a sediment bowl assembly into the tank. The tank itself is not too rusty however, does have a little rust. The outside paint also needs to be redone. Figure I’ll line it and paint it up as nicely as the budget allows. I was thinking of lining the gas tank with either red kote or POR-15. I’ve read some of the other forms, but wondering if anyone has any update a few of their of their tanks after lining them years or months later. My main question, however, is. if anyone has an idea as to how to protect the entrance to the sediment bowl while cleaning and coating the inside of the gas tank. Thanks in advance for any advice on my order of operations choice of products and for helping me figure this out.

What appears to be weld or solder, may be JB Weld. A two part filler. Scratch the surface with a sharp instrument. If it turns shiny, it’s likely solder. If you can’t scratch it, it’s likely weld. If it’s dull, it may be JB Weld or similar. If it’s JB Weld, remove it with a heat gun.

I doubt that the pot metal sediment bowl could be soldered/welded on, metals are different so probably some sort of goop they used

If you use heat, especially a flame, make use you flush the tank a few times with water before you start and the cap is off. Hose and or fire extinguisher handy also not a bad idea

All the information that I have read says that it is better to remove the fuel shutoff assembly from the tank. Your post suggests that you have attempted that and while I have not relined a fuel tank I have removed the valve assembly and encountered some difficulty in the process. First, the thread in the tank is 3/8 tapered pipe threads and difficult to grip the valve assembly well enough to remove it. I used a large vise grip type pliers found that it works better than an open end wrench. Second, be sure to observe/mark the position of the valve before you move it so when you replace it, the fuel line connection is in the right location. If you are successful in removing the valve a pipe plug screwed into the tank will protect the threads for reassembly. JMHO Stan

I use a small oil filter wrench to remove sediment bowls, they wrap around the outside for plenty of grip and does no damage to the sediment bowl

Hey, thanks for the help a little heat and a little wrench Freed it up!

When I remove them, I use a metric wrench, 18mm, if memory serves me correctly. Fits much better than SAE.
