Yep, along with most of the rest of the plane....aft deck, forward deck (to which the canopy is connected), cowling halves, lower cowling. Were it not for having to unscrew the two bolts that hold the gas struts in place and five screws that hold the top cowling on, I could remove the whole top and front of the airplane (spinner to tail) in about three minutes with no tools. I can't wait to do that at the Gathering and show people how a KR is built! The accessiblity that's gained is invaluable to making modifications or repairs, not to mention inspections. I'm sure it cost me a few pounds, but I think it was worth it. > Very neat, complete and well thought out installation - I shall be > referring to these pages constantly during the engine install bit.

Yes, 3/8" fuel lines. Originally I was planning on using CIS injection (and I might still, eventually), so one of those is a return line to the main tank. Lately though I've concocted the idea of a totally redundant electrical/fuel supply system. What this means is that by flipping one double pole double throw switch on the panel I can switch from one ignition coil, condenser, battery, and fuel pump to a whole 'nuther set. So the second fuel line is going to be used to hook that backup fuel pump to, although it has no screen in the tank. That way if something stumbles, you flip one switch and replace every possible electrical problem area with a completely new set. That eliminates a lot of troubleshooting (and head scratching)in about one second, and allows one to concentrate on flying the plane, rather than troubleshooting the problem. The backup battery should let me fly for another hour, which ought to be plenty of time to put it on the ground and see what the deal is. At runup I'd swap systems as a sort of "mag check" process. I don't have a "left/right" tank setup, but a header wing tank and an auxillary wing tank. See http://home.hiwaay.net/~langford/wingtank.html for more details on that.
