Filler Tube Repair Information For Your Imperial

Imperial Homepage -> Repair -> Fuel -> Gas Tank -> Filler Tube

Question from Steve (1963):

Well I sent the gas tank from my buddyís new í63 Imperial off to the shop to have it boiled out and coated. Stupidly I forgot to remove the rubber o-ring where the filler tube fits in and now it is MIA. If anyone has a source or a part number for this o-ring please let me know. Iím going to be in a heap-o-trouble if I canít put it back together because of a silly o-ring


 From Greg:

I removed my gas tank and sent it off to Gas Tank ReNu to be cleaned and coated. While removing the filler tube, I noticed the grommet was deteriorating. It didn't survive the removal and I began searching for another. I called everyone but was told to forget it. I FINALLY found one at Mitchell Motors. I know the guy can be a jerk sometimes and there are members who have had less than pleasant dealings with him, but he was friendly towards me, didn't charge an arm and a leg and got the part out promptly. I was grateful to find it!

From John:

Mitchell's has them. Some folks don't like to do business with them, but they do have what you are looking for. I've spent a lot of money with them & never had any real issues.

From Russell:

Any rubber products company should be able to help you out.

From Roger:

You can go to a automotive supply store and by o-rings. They come in a kit of various sizes. If they don't have a large enough size go to a hydraulic repair shop, Caterpillar, Peterbuilt truck shop, or any other type of large equipment supply outlet. They will have a o-ring that will match yours or close enough to work in its place.

Question from Bill (1964):

Today is the BIG day, the very first time that I have been able to drive my '64 Crown Coupe that I got about 6 weeks ago. I just got back the very well done Master and Booster that I had Karp's rebuild. A friend installed it and got the brakes bled. I had neck surgery about 3 weeks ago and this is really exciting for me as it is only the 3rd time I have driven in the last month, plus it is the first trip in the coupe. It's road trip time!! We slowly and carefully drove down my road into town to feed her. $22.00 and some air in the tires, and we are ready to go. But wait. The attendant says there is gas running all over out of the tank. For the sake of safety, we carefully head back. I get back home and realize that it isn't coming out of the tank, but rather at the junction where the filler neck meets the tank. I didn't get down on the ground and poke around, as I cant do that stuff yet. Bending over though, it looks to me like there might be some gasket or something in between. Is this true? If so what is it? can I make a new one or is it something "special?" If so where can I buy one? Or is it just a fitting that I can snug up ? It will be a few more days before I can get down and play with this, but it is nice to be prepared. 


From Frank:

I think you may be talking about an O-ring that fits at that junction. I have not had to replace mine yet but I have heard it is an easy part to get and common to several years. I think someone even found one at a Chrysler dealer believe it or not!

From Bill:

If it is coming from the filler tube, the sealing item is a grommet that fits into the rear opening of the tank, the tube goes through this grommet. It is a very snug fit that should not require any sealants (live RTV etc). Common to several years is right, easy to get, no. The original part number is discontinued at Chrysler. You just have to look around and find something that fits. They ARE still available from wrecking yards and Mitchell's etc.

Side note: When our tank was seeping fuel, further inspection revealed that it had a bunch of holes on the top surface. Not a pretty sight and very dangerous. A "new" tank was in order.

From Hutch:

I recently purchased one of those grommets from our local Chrysler dealer. The part number is 2880481. It lists at $12.25 and net was $10.41. (i.e. the grommet the fill tube for the gas tank goes into.)
