Re: spica engine miss

[Kevin Trent <trentkc@domain.elided>]

I had a similar problem with my 73 GTV.  Turned out to be a cracked 
injector line down at the pump connection.  Suggest you take it for a run, 
then pull over and look closely to see if there is any leaking fuel around 
the spica pump "towers".  I've had two of these metal injection lines 
break, and they can cause an intermittent miss by fuel starvation.  I 
suppose the lines could break anywhere, but my failures were at the 
pump.  If these lines are not properly supported by the stock clamps and 
hardware, high rpm vibrations will cause them to fail.
