A composite top plate and methods for manufacturing same are described. The top plate includes a metal insert and a non-metallic member. The metal includes a central portion and a flange portion having cut outs to provide an intermittent surface. The non-metallic member is formed on the metal insert and a portion of the non-metallic material is received in the cutouts to thereafter hold the metal fixed relative to the non-metallic member.

The invention is concerned with an improvement in a manually activated fuel priming pump for an internal combustion engine comprising a housing having a barrel communicating at its lower end with a flange disposed transversely to the barrel. A plunger communicates at its upper end with a handle, the plunger being reciprocally mounted in a chamber of the barrel to selectively pump fuel from a first to a second valve located in the flange of the housing. The plunger has around the periphery thereof means slidingly sealing it with low friction against a bore defining the chamber. The improvement of the invention comprises a member co-axial with the plunger and extending therefrom towards the flange and member-bore seal means slidably sealing said member to said bore and disposed to allow flow of said fuel from a space within said chamber between said plunger and said flange to said second valve and to retard flow of said fuel in a reverse direction.
