Fuel Hoses

[smok74]

Hi,

Just wondering if anybody knows the actual size of the original factory fuel lines used in the R33 ? Im referring to the black lines used to link the fuel filter to the fuel rail and also the pressure regulator back to the return line. I've picked up a second R33 that I want to return to factory spec.....

If I want to replace it with some EARLS SUPERSTOCK HOSE, what size would I use ? the 4AN (6.35mm ID) or the 6AN (9.65mm ID) ? Or do I have a better option ?

Thanks

Factory lines are 5/16 or 7.9mm
