I don't stock fuel pipe Delta. We've always use the Nitrile pipe from Planet Silicone on all our own bikes and restorations. It was fitted to my 500 K1 5 years ago, and the 750 K6 10 years ago and it's still fine.

Looks like something has changed, Julie.

This is the stuff I bought and it failed in short order!

as I keep my bike outside, the biggest problem I have is with UV light.  I have hose with cloth exterior but at the point where it joins anything such as the tap, it cracks up within a few months.

Some will say the obvious answer would be to keep the bike indoors but that is not a possibility, it has to sit in an archway.  Sometimes a tarp is thrown over the bike.

I would rather find a UV and Ethanol resilient hose.

Will this fit?

I've ordered a meter of this; I'll let you all know about the fit.
