I truly appreciate your post in this regard. I was going to reply to you separately, but I can see that a reply is embedded in the thread. In case you receive this reply separately from the Antique Automobile bulletin board, I waned to tell you that the reason I asked the original question is because I had purchased a 1946 Dodge Gas tank in order to have it boiled out and then fitted to install into my 1940 Plymouth P-9 Roadking. However, due to some dealings with the fella (the owner of a radiator shop) after I delivered the tank for processing, I immediately took my tank to another radiator shop for inspection after the fella (at the first radiator shop) had cleaned the tank, and then had subsequently lined it. I was informed that the rust had not been completely boiled out of the tank before it was lined, and the application of the lining was inferior since there were spots that were missed, and the lining was thin in other spots as well. I was also told that if the fella lined the tank without first removing the screen in the tank, then he lined the screen and it would be totally plugged and the tank would not in any way dispense any fuel as a result. So when I took the tank back to the original fella, he inspected it and admitted that the lining was defective and would do the lining again (he has since then gone out of business and I have not, unfortunately, been able to reclaim the tanks), but the fella informed me that he was not aware of any screen in the tank. So I truly appreciate your information in this regard.
