Evinrude E155wtlesm part ID help

[bmorse526]

I need help identifying the part in the attached photos. It has a fuel line running to it from the carburetor feed manifold (after fuel pump). Has a grounded wire and one going into the harness. I cannot find it on parts lists or in a manual fuel plumbing diagram.

Any idea what it is and how to troubleshoot would be great.

It is a pressure switch.-----Alarms when suction pressure get too high due to restriction in hoses / filters.----It is clearly shown on the parts page for the VRO pump.

Thank you. Didn't look at the vro diagram. It also shows its on the intake side of the pump not output.
