Broken Spica Injector Line

[Kevin Trent <trentkc@domain.elided>]

About 1200 miles ago my Spica equipped GTV suffered a broken fuel line for 
the #4 injector.  This hard metal fuel line broke at the injection pump 
right above the "nipple" at or under the "cap" which secures it to the 
pump's "tower".   Fortunately I had a spare, and the repair was 
surprisingly easy.  When I replaced the line I was careful to connect both 
ends and tighten gradually to avoid stressing the line, and all of the 
intermediate clamps between the pump and the injector were properly 
installed.   The pump appears to be properly mounted, including the rear 
bracket which connects the pump to the engine mount studs.

Today, I once again broke the new #4 fuel line was in the same place.  I've 
driven Spica Alfas for 15 years and never had this kind of failure until 
now, twice in 1200 miles on the same car (after 10,000 miles since 
acquisition).   This seems to be more than a coincidence!  Any ideas of 
what might be going on?  Can these lines be overtightened?  The only bit of 
(perhaps) relevant info I can add is that in both occasions the car was run 
at WOT in 5th gear for a few miles prior to the failure, however, this is 
not the only time the car was run under such conditions during this period...

Thanks, //kct
