There's still a lack of vacuum, either more leaks or the vacuum source/pump is getting weak...
Is that a diesel?

Passenger side of motor, along the intake, there is a on way check valve in the vacum line. If you can see through it replace it. That solved my problem.
I have no curise also. What line under battery box did you find cracked?

I replaced the line going to the the speed control servo. battery acid
had eaten through the line. it's located under the battery box the line
connects on the back side of servo. hope this helps.
