We are working on a 1922 Centerdoor. We’ve discovered considerable sediment and rust in the gas tank and determined it must be cleaned before this car will run smoothly and reliably. We’ve ordered the supplies to clean and reseal the tank which should be here tomorrow.
Late yesterday afternoon as I was wrapping things up in the shop, I rolled under the Centerdoor to survey the scene and get an idea of what it would take to remove the tank. Unfortunately, the underside of the tank is concealed with the floor boards and I was too tired to start investigating further.
The square tank is under the driver’s seat. What is involved with removing the tank?
You may be able to get the tank out of the seat by taking the bottom seat cushion and frame off. I have removed the entire front seat with the tank included.
Eric, I have the same car, so you'll have to remove the entire front seat including the metal base frame to get the tank out. The metal frame has wood screws around the bottom, which screw into the carpet. The tank will come out with the seat assm. Just as Terry mentioned above.
Well, I removed the gas tank from the Center Door this evening. It was a simple job.
First, I removed the screws holding the base of the seat to the floor board. They were easy to get to by simply pulling up the carpeting edge. There were a total of 12 screws and they were on the back, center, and front (no screws along the side by the door).
Once the screws were removed, I drained the tank. I had to snake a wire up through the petcock on the bottom of the sediment bulb to dislodge the sediment. The next pics show the sediment that drained from the gas tank and collected in the bottom of the jugs.
Next, I removed the gas line from the sediment bulb.
Then I lifted the seat and seat frame off from the gas tank exposing the tank.
The tank was completely free of any obstructions or impediments, so I easily lifted it out of the Center Door.
I removed the sediment bulb and had a little fun scraping out the rusty sediment that was impeding fuel flow and clogging the carburetor.
Below are pics of the inside of the tank. I will be using the tank restoration kit/chemicals to see if we can salvage this thing.
I would think twice about spending any time attempting to restore that tank - knarly !!!
I have a '19 Centerdoor and after having a small gas leak - cracked solder on a seam but smelled like it was huge - I ordered a new tank !
New tank! You don’t want that gasoline smell in a closed car. Ask me how I know. Don
The tank on this 22 Center Door is solid and has no leaks. It is just rusty and gunky.
Good luck with your project !
