Samwel Petcocks

3 products — part of all Petcocks

Samwel petcocks go back to 1916 Harley-Davidson applications — the very beginning of a catalogued replacement parts supply for the earliest production models and custom applications through to the 1940 to 1949 EL, UL, and FL Big Twin and the 1940 to 1949 WL and G Servi-Car, where correct petcock fitment means the right thread, taper, and flow geometry for a gravity-fed fuel system that has no margin for approximation. This is the vintage and pre-war territory that Samwel was founded to cover — the hard-to-find reproduction parts that keep Flathead, Knucklehead, and early Big Twin motorcycles running when standard aftermarket channels have nothing to offer. Getting fuel delivery correct on a pre-1950 Harley-Davidson requires a supplier who understands the specific configurations of each generation, and Samwel's focus on difficult-to-source reproductions is exactly that. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries Samwel through Iron Stable to support UK vintage Harley enthusiasts with access to the components their classic machines deserve.
