My K/5 had a replacement tank when I got it...the hose was crammed and kinked so bad that it was almost impossible to put fuel in....
I had to fix my sending unit anyway so I dropped the tank and ordered some pre-formed 45º hoses and a coupling from here:

I cut about an inch off the straight neck on the tank and modified two of the 45º hoses to come out across the frame rail in the same location as the original.....it now fills with no problem....
Although I had an original steel neck that was in good shape, that I had melted off an old tank.....
I decided not to go through all the hassle of putting it on the new tank because it already had fuel in it and would have to be drained and cleaned before applying heat to it....
And yes..I sold the neck to a member in Alaska.....
