Hi Marc,

An excellant fuel pressure guage can be made by looking in the yellow
pages for companies that make up hydraulic hose or welding supplies.
 Our town's hose shop has guages for less than $10.  Get a foot or so
of  high pressure hose while your there, 5/16 or  7mm I think, double
check, This hose slides over the bleeder screw/ hose barb tee fitting in
the fuel line. It's located near the distributor base,

Anyway, also get a brass tee female thread.  The three ports are: one
for the guage, one for the hose barb, and one for a schraeder valve, its
to bleed air out of theline, and is the same thing as a air valve in a
tire.  NOTE to ensure safe practices  when you are burping the guage,
and are disconnecting after testing.
