    vacuum port adaptors

    I know some of you guys have made your own vacuum adaptors for carb sync, I was hoping for some info on how you do this. Thinking of taking on the infamous home made manometer project.

      Get 4 bolts of the correct diameter & thread pitch, about 2-3 inches long & drill a hole in the center. Cut the heads off & you have your adapters! You will need access to a lathe or need someone that does but, even if you have to pay someone, it should be cheap. Ray.

        Wouldn't it be easier to thread some brass tube? I made some from thick wall brass tube and threaded the end. Use a nut and washer to mount to the port threads.

          That's all the ones from somewhere like motion pro are... I believe Z1 sells "spares" of them.

              Hi,

              I was thinking of picking up a set of these to go with my new Morgan Carbtune.

              << Click

              Only $10.70 for the 6mm tubes. Not bad. I need to order oil filters and shims anyway.

              Thank you for your indulgence,

              BassCliff

                    As nice as the Morgan Carbtune is, the crappy black plastic adaptors included with it are a royal pain in the ... fingers.

                    The brass tubes make things MUCH easier. I use my old Motion Pro brass tubes with a Morgan Carbtune, and life is grand.

                          Question Guys

                          I bought these from Motion Pro but am wondering what you use to cap them when not in use? I thought I saw someone post it a while back but cant find the thread. I am thinking that caps rather than stoppers like motion pro shows

                          Thanks All

                            I just put the screws back in the intake after I'm done....
                            I don't leave the adapters in place...

                              Thanks Baatfam Guess I was thinking of them as a permanent addition but that does make more sense. I was wondering why the 6 mm came with the little white stoppers and the 5 mm didn't
