Hello all,

The carb restoration took me to pay attention to the gas tank and after cleaning and sealing it, I have found that the sediment bulb wont fit. The PO has installed a brass bushing in the outlet and had screwed in a brass elbow leading to a copper line to a flex hose to carb. There was no sediment bulb.

I'd like to restore it to original and would like to remove this brass bushing so that the sediment bulb can fit. any ideas how to remove this bushing without causing damage to the tank?

Also, the tank is round and not oval. Will this cause issues once the sediment bulb is fitted on? not much clearance between the bottom of the tank and the drive shaft down there....

Any help would be most appreciated.

Your profile shows you have a 1925 TT, so I assume that is what you are asking about. Early TT's had a round tank, later TT's an oval tank, so the sediment bulb should not cause a fit problem for you. A round tank is higher and may pose a problem with the seat height of the cab. If you plan to install a Ford cab in the future you will need to use an oval tank, aftermarket cabs will be hit or miss.

Photos of the fittings used would be a help advising you of a course of action. Non standard fittings may need more than usual remedies to make a fix.

Does your tank still have the original flange at the bottom of the tank? If not, I would buy a different tank in good condition. I've paid $50-$100 for them.

Use a wire hand brush or wire brush in power drill and clean well the area around the gas tank lower bung and that brass fitting. Then apply a very good penetrating oil (not WD-40). Let sit a while to do the work to soak down and around the pipe thread brass fitting, then wrench twist the fitting out counter-clockwise. The tank bung is soldered and riveted to the tank so it can take some twist without injury.

We can only guess without knowing what kind of bushing is there and how it is fitted, size, thread, soldered, whatever!

As others have said, we need more information about the brass bushing; whether it is soldered in or just screwed in; and whether it has a hex shoulder on it, as a lot of brass bushings do. If it is not soldered in, and if it has a hex shoulder on it, you're in luck. As others have said, extreme care must be taken, even when just installing or removing the sediment bowl from the tank, much less, a brass bushing to keep from breaking the soldered seal between the tank and the outlet flange. If all else fails, when you have the brass elbow removed, if the bushing won't come out, you can take a hack saw blade and insert it into the threaded bushing and make 2 or 3 cuts through the bushing, being carefull no to damage the threads of the outlet flange.

Thank you for all the replies!

The car is a 1925 model T truck and not a TT. It seems like the bushing is threaded and no hex shoulder. The gas tank is round and fits under the seat in the current cab. Here are the pictures...

As always, really appreciate all the help.

I have used internal pipe wrenches with good results. If it's stubborn carefully slit the bushing first

There is a broken PVC sprinkler pipe extractor tool that looks like a taper reamer.
Comes with 2 sizes of extractor ends. It will bite into your bushing.

Pat has the solution, internal pipe wrench. Jim

My solution if not removing the reducer would be to add an inline glass bowl type sediment bowl with shut off and another shut off at the carb or find a sediment bowl that fits the thread now in the tank.

Here's a bunch of options... https://www.mcmaster.com/products/pipe-extractors/

This one is cheap & easy... https://www.mcmaster.com/products/pipe- ... d-parts-6/

I'll sometimes file four small corners for the edges of the tool to more easily grab.

THANK YOU!

Love this list! Will try one of the ideas!
