Default Write Up: Diagnosing Air Leaks - Vacuum Tank

I had a vacuum leak near the vacuum tank (located under the driver's side fender) on my 82. Since it is a bit challenging to get to there, I thought I would put together a bit of a write up for others looking to repair these. Pictures are at the bottom for reference.


Step 1: Remove the wheel. The lug nuts are 19 mm, so break each one loose and then jack the car in the air. With the car up, remove the lug nuts and take the wheel off the car. Now is probably a good time to wipe the lug nuts clean (use new anti-sieze before re-installing).

Step 2: Now that the wheel is off, you can remove the rear fender liner. The nuts are 10 mm, so a 1/4" socket set will come in handy. When the nuts are off, the finder liner should wiggle out relatively easily.

Step 3: Take your tin snips and start cutting access lines in the fender. Be careful not to cut yourself - that aluminum edge is sharp!

Step 4: Find a large pair of pliers. Grab the access panels you have created, and peel the fender open like you would peel an orange.

Step 5: Now you can easily see the vacuum lines inside the fender. Inspect for leaks.

Step 6: Hmmmmm.

Photos for demonstration:
Inspecting for leaks.


I FOUND THE LEAK!



Access panels provide a good view.


Vent hose is leaking.

Step by step! Good work Tom.

Who knew a new fender would be required to complete this repair.
