Brass Inlet Tube

’67 Volkswagen Beetle — Carb Brass Inlet Tube

This morning, I received a message from a VW friend showing me the new inlet brass tube to his vintage 28 Pict German Solex carburetor.

As many of you know, the brass inlet tube simply is pressed into the port of the carburetor.  With time, this tube can loosen, fall out and be the cause of a devastating fire in the engine compartment.

In the past, I have staked around the tube, which does, indeed, help to prevent its loosening.  Some use J-B Weld or some other epoxy to fix the tube into place.

Tim Robson of Yelm, Washington, who is a Solex carburetor specialist, can remove, tap the port and install a “barbed” inlet tube which never will loosen or fall out.

For those who worry that this tube might spoil the vintage look, let me say that the woven hose, when installed, covers the tube so that it is not visible. I recommend this repair. You don’t want to end up like this.

The Finishing Touches for Your Vintage Volkswagen™

My wife, Neva, and I have been driving and working on VWs since 1976. In fact, we raised our family in these cars. Now, we are retired and enjoy VWs as a hobby. The ’67 Beetle always has been our favorite year. We own a '67 Beetle and a '68 Karmann Ghia.

  1. I want to thank Louis Harris of Dallas, Texas for the illustrating photos of the brass inlet tubes. Lou keeps good records, documenting profusely with top-notch photography! jay


  2. Wish this came out sooner! I just got a carb back from Tim that was rebuilt. Should have had him do this upgrade while he had it.

    Thanks for the great info!


  3. Charlie,

    I got mine back with the standard tube just as I sent it out to him. I had previously used JB weld and staked the tube in as Jay does which works well. The 28 sat on the shelf a few weeks and I decided not to use my old method this time. Peace of mind I guess. I E-mailed Tim and he said just send the top out. I did just that and he put the barbed tube in. Quick turn around too. So, it’s not too late if you can do without the car a few days. Or maybe borrow or use another carb while he does it.


  4. FYI, the fuel pumps have this same problem of coming loose.


    1. Mark,
      Good point! I had forgot about this.


  5. This is so critical to the safety of all VW owners. And once again I want to remind everyone with an air cooled VW to not use inline gas filters in the engine compartment. There is a reason for the VW corporation having designed the fuel hose with no inline filter. They knew that any potential for leaks in this type of engine would have negative consequences. VWs are designed with a filter at the bottom of the gas tank. As long as that filter is functioning you do not need any additional filtering. If you are unsure as to the coalition then maybe it is time to check it. If you absolutely must install an inline filter, then install it behind the firewall under the car frame. I believe this website has a video regarding this matter.


    1. Kevin,
      Well said. I’ve learned so much through this site.
