Hi Santiago,Everybody is right about using 3/8" lines. Please be sure you haveexcellent books or references to follow as you construct your fuelsystem as this is the NUMBER ONE cause of engine failures. You can'tdo better than the Tony Bingeles books for starters. Be sure you useflexible tubing where needed for vibration, avoid running the linesuphill anywhere, install a gascolator at the lowest point for water, ANDmake sure your tank sump in the wing tank is at the lowest point andwill drain all the water from the tank WHEN THE PLANE IS ON THE GROUND. Be sure to install a screen finger filter in the tank, and an inlinefuel filter that you can ck easily and that is easily replacable, withyour gascolator being the third filter in the system. It astounds mehow much stuff shows up in my inline filter even after I've assuredmyself that the system is completely clean. Found what looked like rustthe other day and there is NO steel in the entire system, including thetank (my engine is on a test stand) which goes to show you how manyforeign objects are introduced into our fuel systems from the pump.In short, this system seems simple, and it is, but it demands perfectionin design and assembly because it could hold your life in it's hands andit has proven historically to be a problematic system.Douwe________________________________________________________________________________Date: Thu, 1 Jun 2006 16:33:05 -0400
