REFLECTOR: Long Bulkhead Fitting

[Brian Michalk]

I have some AN6 fittings that go through the firewall, but rerouting my 
fuel lines requires that I use a bulkhead fitting where there are more 
layups.  The problem now is that the fitting is not long enough to take 
the nut.  It's long enough for the flare nut, but not the bulkhead nut.

I can't seem to find a longer fitting.  What's the solution for this 
problem?
