To me, it's a waste of time buying a fuel pressure gauge that's not accurate enough to do an injector balance test and only use it to check press/vol. Gauges I can afford are things like Actron which are only +/- 2psi mid-scale (I called the company), and I'm sure you have something that's +/- 1psi full-scale (and made in US).

No, I mean you need to pop the seal out of the cap and insert a new one. They have a bad tendancy to not reseal......
You really do not need +/- 1PSIG accuracy; most of the time, you either have pressure within range, or little to no pressure at all. I think the unit we use is also +/- 2 PSIG, and it is just fine for this type of test.
