Fuel return line sensor

[alta 930]

I am looking to rebuild the return fuel line that goes to the WUR, there is a sensor of some sort that was not connected and I cannot find any information on what it could be. The line is the one with the red tape on it and the sensor is yellow. any help as to what it is would be greatly appreciated

Not positive but that looks like a solenoid valve not a sensor. Probably had a fuel enrichment delay circuit attached to it. Check resistance on the plug terminals and see if it changes with fuel pressure.

It's certainly not a stock item. I agree it's a solenoid of sorts. Otherwise ignore it's even there if not hooked up to something.
