There are many different versions of the warm-up regulator! The only way to know what engine that that regulator was designed for is to find the "Bosch" number & cross-reference it to the correct application.

Many applications use different vacuum ports to accomplish the SAME results. The only way to know what your system is doing is to hook up fuel pressure gauges to the system & monitor the fuel pressure changes.
