Don't think I would be happy unless the actual pressure was known, we have a 2.5 bar regulator so any place you open the Fuel System should be fairly dramatic. Is this going to be a big problem.

I ordered a new sensor as this one is shot. check over here and the other Lead on the Battery Positive, [not using the Meter at all] then touching the other end of the Leads to Injector side pins, I don't believe it matters Plugs are still in good condition and spark nicely when out.
