I Found The Leak, Now How Do I Fix It?
1998 4x4 EDDIE BAUER EXPEDITION 5.4L
Hello all! In response to my last post about my airflow coming out of my defrost vents instead of my dash vents, someone told me to look behind my battery for a vacuum leak. I did that and found the leak right away. We have patched up the tube but it still needs to be replaced. We clearly see one end of the tube but the other end goes into a hole in what I beleive is the firewall. How do I get in there to get to the other end of the tube? Do I have to have the dash taken out? Thanks again for help with my last post and thanks in advance to anyone who can help me now.

Can you do a permanent repair to the section of hose you can access? Meaning - cut out the bad section and hose barb/union a new piece onto the section that goes through the firewall. That way you replace a few inches easily rather than the potentially difficult job of doing the whole hose. Just a thought.

Thanks Darth Baiter for your reply. I was thinking that I had to replace the whole thing in order to ensure that there was no longer a leak. I really don't know anything about fixing things on a auto but as I have been coming to this site I have learned a wealth of information. So could you tell me what I need to do to barb/union the new piece onto the hose? Right now it is patched but it is still leaking a little cause the airflow still swiches to the dash every now and again but only for a few seconds at a time. Thanks again

You might try bringing the vehicle to any of the large chain parts stores and talk to them about solutions. IMO you need a section of hose with the same ID (inside diameter) as the existing hose and a barbed union - a small plastic piece of which half fits inside the old hose and the other half fits in the new piece. This union is hollow allowing vacuum, fluids, air, whatever to pass through. If you trace any of the other vacuum lines and you see a T fitting that joins 3 hoses - that's probably a barbed junction. All you want to do is join 2 pieces - a good parts store will know what you need. Or try a plumber - cause that's what you're doing; plumbing. The best repair would be to replace the entire hose, you may still have to do that. Try the bandaid approach first. I'm not sure I can help any further. Good Luck.
