Re: Spica inlet leaking

["Dean W. Cains" <dwc@xxxxxx>]

Hi Stefano:

Does it really only leak when the engine is running?  How about with just 
the rear fuel pump running?  The last time I reinstalled the Spica pump on 
my '74 Spider, I had what looked like a similar leak.  It was actually 
leaking from one of the injector line check valves.  Those are the fittings 
directly below the injector lines, but above the top surface of the 
pump.  The line was tight to the check valve fitting, but the valve was 
loose in the pump body.  If that's your problem, the leak will only occur 
with the engine running, since that part of the pump is only pressurized 
when the engine is running.  If it's really a leak from the fuel inlet, it 
should leak with the ignition on, even with the engine not running, since 
the rear fuel pump will be pressurizing the fuel inlet.  If it is leaking 
from the fuel inlet, and a new washer doesn't work well enough, try a few 
turns of Teflon tape on the threads.

Regards,

Dean
