Pretty incredibly, the bolt from the banjo adapter
at the cold start injector was the same thread as
a Ford adapter I had. After going through my X1/9
parts boxes, I found the proper copper spacers.
So what I did was to fit the bolt facing away from the
cold start injector and bolt this on, and connect it
to the gauge. (for the curious, this is a gauge I
bought at autozone and comes with the Ford
adapter and without it supports chrysler/GM; their
number is CP7818).

I left the other end connected to the fuel rail. I removed
the tachymetric relay, and put a switch in it's place
(eveybody who plays with bosch l-jet has made a
switch like that). Energize the fuel pumps, the
pressure goes to 40 psi which is within norm for
my N9TE engine (the N9T is higher). If I stop
energizing the fuel pumps, it rapidly drops to
20 psi, and then go down a little slower to 0.

That sounds like a leaky injector, doesn't it?
