wayne :

Hi I'm Wayne, I will help you with this,

wayne :

This sounds to me that your loosing vacuum over night, and that explains the hard pedal, when you start engine, vacuum pump rebuilds the tank, and all works normal

wayne :

It's very,very hard to find a vacuum leak, best thing to do is tighten all fittings on tank and lines

Customer :

How do I fix the problem and is it damaging any thing . Paul

Customer :

Where approx is the vacuum tank

Customer :

Are you still there Wayne ?

wayne :

Vacuum Tank is normally on the frame rail of truck, some time times Curb side........

wayne :

Will it hurt any thing.....NO.....just have to wait and rebuild Vacuum

wayne :

Fix the problem, Like I said, finding a Vacuum leak Very hard, Air leak easy, soap bubbles. can not do that with this
