Need ideas on how to deal with bed floor ridges on fuel filler

[72farmer]

I have spent the last 2 hours looking at post's here with no ideas.I just bought a Boyd's EFI under the bed fuel top fill tank.I also bought there bed fill flush mount kit to fit the tank.You have to remove there cap and attach a short piece of 2" rubber hose from tank filler neck to flush mount filler. I have 2 questions.
1-If I use this floor flush mount kit (or any other door)how will I deal with the high low ridges in bed floor not allowing it to be flat on the bed floor?
2-The 2" rubber hose from tank filler neck to flush mount floor filler is a very tight fit and I can't imagine how I could ever get the hose off tank if I had to drop tank down?
I think now I may not use the flush mount kit and just buy a door of some kind and use gas cap that comes with Boyd's tank.But how would I deal with bed floor ridges?This is the door I was thinking about.
