I have a 1050 Holley Dominator that the intermediate booster tube has come loose in the main body.
This tube is just above the top of the butterfly. It moved out 1/4 inch or so and held the butterfly open. Tube is in good shape just loose. What holds these tubes tight are they glued in or tapered. If glued in what do I need to use. Thanks

They just tap in. Usually not loose but I’ve had to use loctite on a few to hold them in place.

Take some plyers and squeeze it in the middle just a little to snug it as you tap it back in. Add a little green Loctite to it as well.

Thanks Mark did what you said and we are good to go thanks Kevin
