Default Please need help now

Ok I got a vacume leak somewhere I'm trying to find.
I hear this loud hissing beneath the passenger fuel rail cover. I took it off and see two seemingly dissconnected hoses sitting there. There is also two places on the engine it looks like hoses go to. One hose is going to the bottom one and connects at a different place in the engine. The other connection is where the loud sucking sound is coming from(the top one). Is this right, or is this a problem.
Sorry I dont have a picture.
Can someone take off the passenger fuel rail cover and see for me. Or if you know already.
I am trying to figure out where the vacume leak is coming from because my cuise control doesnt work and my AC only blowes out the defroster.
Thanks!

ok I just bought a T connector and attached the three places and replaced one hose that some battery acid ate through. Now every thing works :D :D
I got my AC to work now and my cruise control works :D

Sorry that I did not post sooner. This is a common problem where hoses are susceptible to damage. A common problem is when vacuum hoses are near fuel lines or injection systems where fuel can leak. Many times, fuel leaks on the hoses and make them soft. When this happens, it is just a matter of time before it leaks vacuum. When there is a leak, many systems can have problems such as the defroster/HVAC system and more noticeably the cruise control. I am glad that you were able to fix the problem on your own. Good Job! :D :cheers: :cheers: :D
