Lezyne gravel floor pump chuck

I have the screw on version of the chuck on the Lezyne digital drive gravel pump - looking to replace with the push on version.

Two questions - best model? And - Installation. Just chop the old one off and connect the new?

Thanks

The lezyne push on is crap imo, so just skip it. That leaves you Arundel, Presta, and Silca. Each of them should thread into the schrader side of your gravel chuck. I had the arundle one but preferred the locking chuck instead just b/c the push on didn’t operate at 90 degree. So the presta one might be better Prestacycle Pro Presta Head with Pump Hose Adapter Bundle
