Hy Jay_Brown, I'm sorry if the hose p/n I quoted did not match the hose that was on your truck, it has been 66 years since a 1946 truck was built, and myself and others can only quote the numbers that the parts books tell us were the original equipment on the truck in question. I don't think any of us can tell how many times a given truck is worked on, and possibly modified from it's original design. I have used this same hose on a few of my trucks and others that I have worked on for other people, with no fitment issues. If you would like to tell us the length of the hose in question, and what the threads are that are on the line you're trying to replace, I will do my best to find a p/n which matches your specifications.
