Re: buying fuel line for HPDI ? after the VST
dunno
I am a yamaha tech and if needed I look it up and install the correct part.
that little line between the VST and the medium pressure inline filter is a kit,comes with 2 clips and a 2" section of line for about 70 bucks.
whatever you use it must have a burst pressure rated at 300 PSI and the correct clips must be used t retain it.
50 PSI fuel leaks can be nasty.
