I'm not aware of a reason for not using Kunifer, I think my Firenza might have been done in that but it's so long ago now I can't really remember.
Looking in the parts book, it says this:
1256cc engine - CX101001-CX219999, CY101001-CY199999 PIPE, tank to pump (NLS, cut from 2688574 roll)
1256cc engine - DX100001-FX199999, DY100001--EY120847 PIPE, tank to pump (NLS, cut from 2688574 roll)
1759cc / 2279cc engine - CX101001-CX219999, CY101001-CY199999 PIPE, tank to hose (NLS, cut from 2688574 roll)
1759cc / 2279cc engine - DX100001-FX199999, DY100001-EY120847 PIPE, tank to hose (NLS, cut from 91008607 roll)
And the rolls:
2688574 TUBING, Bundy, 3/16" OD x 25ft length
2688575 TUBING, Bundy, 1/4" OD x 25ft length (NLS, use 91008607)
So it looks like all OHV and early OHC used 3/16", and later OHC used 1/4" pipe.
