Bay Window Fuel Sender Access Hatch

[Doob]

I have a 1971 Bay Kombi. I had the engine & fuel tank out a couple years ago. I took the opportunity to take some measurements of the fuel tank & fuel tank cavity - including the location of the fuel gauge sender unit. I know there is some variation in the fuel gauge sender unit and the fuel tank between different models of the Bay Kombi. I am not sure how much variation there is in the location of the sender unit in relation to the cargo bay floor plan?
Anyway - the 2 pdf attachments here give the approximate dimensions & layout for my 1971 Kombi.
Cheers
