Temu pressure bleeder kit arrived today Dave. Was expecting several various size m/cylinder caps but only one included. Checked and it does fit on reservoir although not convinced I could screw it fully home as similar on my Roadster has heat proof material wrapped around it due to exhaust manifold proximity. This would easily be removed though as just secured by cable tie. My question therefore is did you dismiss the included plastic cap as thread incorrect or did not provide airtight fit? Also where did you get alternate cap from, which presumably didn't have matching q/r male fitting, hence the short rubber hose adaptor?
