Suspension Dump light low pressure switch

[Fullerr]

Recently after replacing rear air bags on my 84FC, I discovered air leaking out of an electrical pressure switch located on the front right/ rear air bag. See pictures. This switch activates and deactivates the suspension dump light on my dash.

The replacement Bendix part number is BEN276599, 30 PSI switch. See picture with cross referenced part numbers.

If it wasn’t so lazy, I may have been able to make a new gasket for the old switch.

As you can see from my selfie, I’m still waiting to discover a job under the bus that doesn’t require a shower when completed. Lol

Just FYI....

If I remember correctly, that gasket isn't what seals the air from leaking, and I believe there's a notch in the housing to allow ambient air pressure on the spring side of the diaphragm.

The 'seal' is an o-ring down in the base housing. If you pull that out and clean it up and lube it, they usually quit leaking.
