Hi

I bought the metal pumphead for the Topeak JoeBlow Booster (recommended by someone on here) or at least it seems to be designed for a whole series of Topeak track pumps…

I removed the old tube from the pump and it left behind the adapter, seemingly wedged SUPER tight in the fitting. And the new tube also has an adapter pre-installed in it which is also mega-tightly inserted. I’m 99% sure these are the same and I need to remove one but I tried using pliers to pull one out and it ain’t shifting without destroying it which I don’t want to risk. Am I being dim?

Slide a pokey tool* under the rubber tube and spray in some kind of lubricating liquid (soapy water, plain water, alcohol, etc) into the junction. It should slide off a bit more easily.

*A “pokey tool” can be as simple as an old spoke that has been sharpened on a grinder.

It looks as if the fitting with the white goop on the barb can be pulled out of the threaded portion it's in. If so, then maybe the hose with it's fitting can be screwed in there. But that depends on if it's threaded ferrule is the same as what is on the left.

If not maybe you can just cut the hose at it's fitting and remove it's threaded ferrule, or what ever the proper name is... and then use the barbed fitting and the threaded ferrule from the old pump hose.

Essentially what ever you have to do to make the hose stay connected to the pump. Since you didn't get replacement parts that are "plug & play"! <grin>

PUSH the Tubing off of the fitting... do not Pull.. PUSH the tubing loose... i use a flat blade screwdriver slipped in between the tubing and fittings, then use a combo of twisting the screwdriver, alternating with pushing the tubing
i just did this yesterday to remove a barbed fitting from a brake bleeder hose.
i've done this with thousands of stubborn vacuum and fuel lines over the years.
PUSH, don't Pull.

also,Heating the Tubing will soften it for release... hot water helps a lot.

hold fitting, PUSH the tubing, away from the fitting. work one position, then an opposite position.... it will only move a tiny bit at first... keep at it.
pushing expands the tube... pulling only makes it tighter.

and the old tube can be sliced, carefully, to get it to release., as recommended earlier.

stretchy tubes are just like a chinese finger lock.

I'd just cut the old one off. If you don't want to do that you could try warming the hose, without melting the fitting - dunking in a pan of boiling water can do it, both for removing the old fitting and attaching the new one.

The old one is gone, it’s not a problem, but it has left the adapter behind, that’s what is in the way (and presumably will also fit the new tube if it remains in place). Will try getting something between the new tube and its pre-installed adapter but damn that thing is tight and there’s almost nothing of the adapter to hold on to, as you can see in the photo. But I get the push vs pull thing. Thanks, will continue the quest…

This worked perfectly, thanks a lot
