I'm a new beetle own and I found this cut vacuum line underneath and can't seem to find where it connects. It runs under the trunk and travels from the gas tank around and down through the driver's side wheel well, underneath and across by the Fuel filter and fuel pump. She just won't stay running. Any help would be greatly appreciated.

stay running and I'm gonna assume this is a problem as it will run with starter fluid but dies.

Have you tried plugging the vacuum line to see if it will run. The only vacuum is at the carburetor or intake manifold. Fuel tank may have a vapor line if smog equipped. American cars bsck then used vacuum to control heater and defrost vent doors.

Perhaps its an optical illusion but in the third picture it looks like your steering shaft is almost rusted through.

The hose does not look like a factory hose. if it was a vacuum line then you would find the other end attached to the base of the carburetor or intake manifold somewhere. There is nowhere else it could go. If it was for vacuum, then you would feel it by putting your finger over the hose end while the engine is running. As JohnNewb suggested, you could try plugging the line with a golf tee or piece of metal shaft. if this line was a vacuum line and it is plugged but the engine does not run, your problem is elsewhere.

If you think you have a vacuum leak check the following:
1. look for an adapter plate under the carburetor with a large vacuum fitting sticking out.
2. look for a vacuum fitting on the drivers side of the intake manifold just above where the manifold attaches to the head.
3. if the distributor has two vacuum lines, find the one closest to the distributor body and follow it up to the base of the carb.

In each case those lines would have significant vacuum at idle speeds and affect the ability of the engine to idle. There is also a venturi vacuum coming from the throttle plate area through a connection on the left side of the carb, that runs to the distributor connection furthest from the distributor body. This vacuum will not affect idle as it is only present when the throttle is opened.

Was the engine running ok and then suddenly stopped running (being able to idle on its own)? Did it run ok but over some time get harder to keep running to the point it will not stay running on its own?

Jimmy,
Did you get this fixed? Would be interesting to see what that plastic line hooked to and if it is really a vacuum line.
