I installed metal pipes from an '85.

I see what you mean. The metal pipes were used on gas and diesel
models. Searching BD website, shows a fuel tank with 70mm fill hole
for diesel

During the air cooled to water cooled swap, I installed the coolant
pipes before fuel tank. IIRC, there weren't any screw holes for the
pipe support clamps, or, since I made one or two of the clamps, I may
have drilled new holes that were slightly off the mark. Either that or
the P-side pipe is turned slightly toward the P-side.
