Yes KpA. LP generally stays at same value (unless the pump is knackered). HP should be around 28000 at tickover, but rises to over 100000 at high engine load & revs.

Plenty of KPA to PSI or BAR converters online, so just let us know what your diagnostic says. 28000 KpA is about 4000psi, hence why any fuel leaks go everywhere !!
