2002 f115 no water to pressure gauge

[jds75]

My pressure change stopped working, line from motor is clear, disconnected at motor and no water from adapter Nipple. Tell tail is strong and no overheating. Any advise appreciated TIA

Shouldn’t be any water in the tube. The gauge works by water pressuring the air trapped in the line to the gauge.

Remove adaptor to clean or try to unclog adaptor with some kind of probe.

Does gauge work if you blow on the tube?

I will check.
