Diesel Fuel in T-handle Vacuum Gauge

[mmarin]

Men,

Yesterday I noticed I had diesel fuel in my Racor T-handle Vaccum Restriction Indicator Guage.

Not certain, but I thought there should only be a vacuum here? I did pull
the fuel filters and they were getting cruddy... perhaps the fuel filter simply
"filled" up?

Any thoughts would be appreciated?

Thanks,

Marc

Perhaps there is a failure of the membrane in the gauge.

Can you show a picture? I'm not sure if you are confusing the bubble in the silicone oil of the gauge with something else.

Those gauges are/should be liquid filled.

From the Racor brochure: "... After September 1999, Racor converted many liquid filled gauges to new silicone dampened movement. This new (dry) technology provides a vibration resistant design that never leaks fluid or requires adjustments due to temperature or altitude variations."

Apparently the later versions of this guage should never have any liquid in side.
