Vincent Top Quality Petrol Taps MADE IN ENGLAND Fit & Forget. Also read full listing description (Blue Link at bottom). Two Lever Arm Petrol Taps, one with an internal fuel tube making it the main tap and one without a tube making it the reserve Tap. 1/4 BSP Thread at both ends & complete with copper sealing washers. Featuring a tapered brass fuel seal with ethanol resistant o ring unlike some other makes which look very similar but have a noticably different filter, a smoother plated finish and a parallel fuel seal rotating inside a full rubber insert. This rubber insert has been known to turn in service & partially block off the fuel flow. If this happens it can cause your engine to run lean. Not good.
