Yeah they are, I too used extra tubing to extend them, and I put the regulator on the back to make it a little cleaner, but wasn't sure about the compression fittings yet and didn't want to run them over the cross over at the rear of the blower, so I am just feeling it out, and will probably go the same route Scotty did when it goes back together, my boss recently bought a huge assortment of compression fittings for the shop and think he might have to donate a few to the cause. Those things get expensive quick at 3-4 bucks a pop. I learned that quick when I made my own new fuel lines for my black 99 coupe a few years ago.
