Red58, thank you for your effort. Since I am not doing any kind of final configuration of the filler set-up, it does not matter to me what style of filler neck I find. My filler neck will be simply, if not primitively, in the middle of my bed and protruding up through the bed. Obviously not convenient and not pretty, but it will have to do for now because I am not able to get materials and do the necessary welding yet for a more cosmetically pleasing arrangement. As such, if your 'TF' filler neck has a 1.25" o.d., it seems to me that it certainly fits into my 1 3/8" i.d. hose. It would then be up to a hose clamp to seal it. The difference of 1/8" remaining between my hose and your neck is, practically speaking, only a 1/16" difference. I think a hose clamp should have no problem with that. Please let me know if you have a photo and an asking price for it.
Bartamos, the reason I converted to fortieths of an inch was to get a more visual comparison of how the two pieces mate. With my math skills, it is easier for me to just find a common denominator. I know it looked funny, but it fell nicely into my head, lol.
Thank you, gentlemen! -Alden
