Nubs Posted April 28, 2020 Share Posted April 28, 2020 I was hoping somebody could help? Looking for a fuel tank drain plug for a 1951 chrysler windsor deluxe. I have found fuel tanks but my tank is okay the plug itself I need to replace the head broke off. Can't seem to find one, any help would be greatly appreciated.

JFranklin Posted April 28, 2020 Share Posted April 28, 2020 Try a NAPA auto parts store. Take your fitting with you. Link to comment Share on other sites More sharing options...
Nubs Posted April 29, 2020 Author Share Posted April 29, 2020 Thanks, I do have to go there for a 6v dir flasher. I will bring what's left of it and see if they can match it. Link to comment Share on other sites More sharing options...
JACK M Posted April 29, 2020 Share Posted April 29, 2020 I will guess it just a regular NPT plug. Available with a couple of different ways to drive it. Link to comment Share on other sites More sharing options...
Nubs Posted April 30, 2020 Author Share Posted April 30, 2020 No, not a standard plug. Can't seem to find it anywhere. Tried Napa, Sanel Auto Parts, Fisher Auto Parts, Fastenal, Fasteners Warehouse, have a call in to Andy bernbaum I have had no response in a few days. Checked online, and also talked to some old Chrysler mechanics, and have had no luck finding one. Hate to replaced the whole tank at $400 when all I need is just the plug.

sagefinds Posted April 30, 2020 Share Posted April 30, 2020 Is it something that is not a standard pipe thread? Can you post a picture of what you have at all? Link to comment Share on other sites More sharing options...
JFranklin Posted April 30, 2020 Share Posted April 30, 2020 Contact a machinist they should be able to turn out something for you. Got a friend with a lathe? Link to comment Share on other sites More sharing options...
Nubs Posted April 30, 2020 Author Share Posted April 30, 2020 I can try that, thanks for the suggestion. Link to comment Share on other sites More sharing options...
Matt Harwood Posted April 30, 2020 Share Posted April 30, 2020 I can't believe it's not a standard pipe thread. The one in my 1941 Buick is 1/4 NPT and I'm pretty sure the one in my wife's '56 Chrysler is 3/8 NPT. Go buy a few brass plugs from Home Depot and see if one fits. It can't be a thread that Chrysler just made up for their gas tanks. There would be no reason and would add a significant degree of difficulty and cost to both manufacturing and service. Have the threads been damaged, making it impossible to thread anything in there? You might be able to chase it with an appropriately-sized tap to get it right again or go up to the next size if you're careful. 2 Link to comment Share on other sites More sharing options...
JACK M Posted April 30, 2020 Share Posted April 30, 2020 (edited) With all that said, the 46-48 Chryslers (could be others) used a special fitting on the draw tube that doesn't fit anything else and is difficult but not impossible to find. There was a discussion on that a couple of years ago that may lead one to a drain plug if it is indeed an oddball. Seems there was a supplier mentioned as I remember buying one of those special upper fittings.

Ron Lawson Posted May 15, 2020 Share Posted May 15, 2020 Make sure you put a new rubber washer on the new plug Link to comment Share on other sites More sharing options...
Batwing-8 Posted June 14, 2020 Share Posted June 14, 2020 I'd recommend a soft lead or copper flat washer. Rubber compresses and may embrittle. Then you have no washer. Link to comment Share on other sites More sharing options...
