Just found them on ebay from a shop in Texas for $146 with free shipping and another $31 for the SS clamps. JD Motorsport in UK has them for about $120 plus 11 bucks shipping but I haven't found Samco direct. JD listing says it includes the Samco "clips" I just sent a note to the UK to clarify if they are using the term "clips" for what we call "clamps". The listing pic shows clamps with it but further down in the product description it says clamps are also available. Clarifying all now.
Steve, what was difficult about the installation. I assume the tank must be removed to install all of the hoses. I think there are five, correct?
