I got a chance to work on this over the weekend. I ordered up an aluminum 90 degree elbow and the Super 45 degree rubber hose and got to work.

I let the fuel level in my tanks get low so I could hopefully pull the fill hose without pouring fuel all over the driveway. How low? I don't know, b/c the sender unit that came with the new tank has read weird the entire time. So I cleaned up the old sender, which always read well for me and plunked it in.
Then came fitting the aluminum elbow. When placed through the hole in the inner quarter, the neck was too long to join up with the fill port. So I measured a bunch of times and cut it. I cut it well, but to hit the fill port, the outlet of the elbow would be pointing towards the underside of the Pig, not at the tank inlet. If I pointed it at the tank inlet, I could not hit the fill port. Hmm...
Javeline had a date with Project Moviestar, so I had to keep things rolling. I opted to see if the Super 45 could work. The more I looked at the angles, I thought it could. I remember
@scrapdaddy saying it did not work for him, but I thought I might have some different angles in play on my '74.
Long story short, it works really, really well! I measured a bunch of times, and then measured a bunch more times, but I got the bend in just the right place, and I really like the final fit.
I went to the gas station and put in 18 gallons and it filled really well, no problems, no fuel gushing back out down the side of my Pig. I also shortened up the overflow line, don't know if that was part of my problem? You can see in the Before and After how I had a dip in both the fill line and overflow line before, and then a nice, smooth run in both lines after.
And the gauge reads full again! Nice when things work!
