Update cont....
So after lowering the tank, it now interferes with the frame rail. Didn't want to cut the frame rail so I cut the tank fill tube
Worked out great, plenty of room to clear the frame now.
For now I did a temporary 45 degree coolant hose I had laying around for the temp bed floor I installed. Eventually I will route the filler neck somewhere else like rear bed stake or something. Haven't made a decision on this yet.
Again, very temporary for now. But it should work for a while. I still need to pull the bed apart again, this is just for mockup, and then I will get it back together a little better.
