Yes. Keep in mind there are two critical pressures with K-Jet. The line pressure (to the injectors) and the control pressure (to the plungers).

The control pressure should be (IIRC) significantly less than the line pressure, and it should vary depending on any number of conditions (depending on what the CPR is designed to react to). The line pressure should be stable, period. If it's not, the accumulator has probably failed. The control pressure can't really be adjusted (but the CPRs, especially the early ones, can be cleaned pretty easily). The line pressure can be adjusted with shims in the fuel distributor, but the main pumps do wear out, eventually.
