I've always wondered what people mean when they say CIS fuel pressure gauges?

Are they thinking of dual AC manifold gauges you use to check the suction low side and discharge high side of automotive air conditioning or something?

It's one single 0-100 psi fuel pressure gauge with a ball valve in the line for checking CIS... not gauges as in more than one gauge.

A wideband AFR gauge would be more helpful to diagnose the problem you're having.
