dkmorgan, the question is, will you be able to duplicate the same tank elevation in relation to the venturi in the plane as you did on your test rig? I think this is the biggest problem people have with inverted installations. Depending on the profile of the forward fuse area, it's sometimes very difficult to mount the tank low enough in the fuel tank compartment to prevent siphoning.

redneck, Central Hobbies sells a remote "Headlock" or you can make your own pretty easily if you're a tinkerer.
