FS: New Fuel Hose to go between the two fuel rails
 

Porsche does not sell the fuel hose that connects both fuel rails. If your hose becomes punctured or fails, you will be forced to buy a new fuel rail (at a cost of $600+).

Based upon some research, it looks like Porsche used a Polyamide/nylon type hose with a rubber surround. No manufacture sells a polyamide hose in a 9.5MM (or 3/8") diameter. Wayne Dempsey used regular fuel hose in his 101 projects book with dual fuel hose clamps on each side. I purchased a 25 foot roll (thats all I could buy) of some high quality goodyear/continental hose and used some on my car with some oetiker high pressure crimp style clamps. Consequently, I have enough hose left for 6 kits. One kit contains a 3 foot section of the hose and four oetiker high pressure crimp-style clamps. I am asking $25/each shipped to your location. This is just purely the cost of the hose, clamps and shipping. I can do $17/shipped for just the hose section.
