If you've not yet worked significantly on the firewall forward portion of your RV airplane project, let me warn you: fuel and oil lines are unbelievably expensive. I learned that lesson the hard way: Buying the stock fuel and oil lines based on Van's drawings.
There are too many engine combinations (mine is an IO-360 from Mattituck with vertical updraft) to make buying stock fuel lines worthwhile. Even if you could get them to fit on your engine, you'll likely be making some concessions to efficiency -- and maybe even safety -- to get them to fit.
It's possible, of course, to have your fuel and oil lines custom built, and certainly there are plenty of RVers out there with enough money to build their airplanes merely by writing checks. I am not one of those people, however, and I strongly believe in the basis for building your own airplane: recreation and education. I've learned so much from building my RV-7A so far, that I enjoy the challenge of understanding how things work.
