Seems like I may need to rethink this choice. |
Replace ASAP!!

| Update: In the '60-61 thread someone showed me the exact tank mine has. I ordered a cap from them, and that solved the issue of fumes. Apparently the old cap I had was stripped out. New one seals great. |
Do beware, if you remove the new cap and notice a hiss, that means the cap is not vented. This can cause:
1. That will cause a build up of gas/air pressure in hot weather which will push fuel thru the carb when parked, flooding the engine with fuel and thinning out or even flooding the sump oil. Too much fluid in the sump can even flood the engine enough that it gets past the rings of one or more pistons and at start up hydro-lock, possibly even bending up a piston rod.
2. While driving the fuel being sucked out of the tank can no longer be replaced with air from outside the tank causing a vacuum to build up. This can even cause fuel starvation to the engine, enough to shut it down.
3. Due to the two forces flexing the tank walls in/outward over and over, sooner or later the steel will fracture and leak fuel. |
I just replaced the cap with the vented one and when I removed the non-vented one, it did exactly like you said in #2, and I hadn't driven it very far.
Thanks again to everybody here for all the advice on this. I would otherwise have had no clue that the non vented cap could be so problematic |

Well that is why many of us old timers are here on this very website! Personally Barb&I owe a huge debt to the previous old timers that helped us out back in the 1980 thru 1990s back way before the internet was a big thing. By now most of those folks have gone on to the VW wrecking yard in the sky. Wish we could go back in time and thank them one and all. Figure next best thing is to try to help any other VW owners, doubly so for the next newbie. We just ask that if you can down the road, pass it on forward. Even if it is not a VW related problem, the world needs more constructive dialogue.
Do not feel that you can not ask questions here about a part you are thinking about buying before you do so, especially if it is not a stock part. We have made some majorly bad VW decisions in the past and paid for it dearly later in time and $$$. If we can help will be happy to, others here will fill in when we can not or forget to mention a detail we skipped over. That is the beauty of the forums here.

Very much appreciated! And although I owned a few Beetles back in the '80s, it's been many years before the one I currently own since I had one so forgot much of what I knew. Plus, I always had the 40 horse (or later) Beetles back then so the 36 horse I have now is different in many ways, I am learning! |
