So my camper isn't that old yet, 2013. Apparently most fuel hoses they sell now have a "reverse outer flange" and the older style is NPT. An attempt to find a hose longer than 12 inches with an NPT end was in vain. So with this part and "alto" I was able to buy myself a 48" tank hose! I have a 48" tank hose with an NPT end! Works great!
