Fuel pressure sensor question

Want a job Don? ;-)

Since we don't know if the ramp rate of the sensors is the same it's best to use both.

The vaporworx sensor should be installed near the outlet of the fuel module to help reduce the chances of picking up pressure pulses from the fuel injectors/mechanical pump. The pulses can cause an unstable idle/light cruise fuel pressure instability. GM typically puts the sensor near the same location as well for the same purpose.



The ECM sensor, unless otherwise specified, can go near or on the engine fuel rail.
