Sump Air Problem

[Kevin Ford]

All:
I was getting ready to pull out this morning with my '82 PT-40 and the
sump warning light will not go out. After airing up the front and rear
air gauges show to be normal, but the Tag gauge is 0 PSI. The tag
airbags and the front airbags are "not" aired up, but I do not hear any
air leakage.

Anyone have any ideas, before I cancel my vacation?

Thanks.
