Have a OS FS 120 III with leaking fuel system. Is there an aftermarket "durable" fuel pumping system for my engine? Thanks in advance.

Would a Cline Fuel Regulator, http://www.billsroom.com/pcfs/produc...uelsysdesc.htm, perhaps work as well? It would probably be simpler to install and there is no pump to adjust. Just readjust the carb to work with the regulator.

The OS pumped engine already has a regulator built into the carburetor

Reference the Cline suggestion: As Gilda Radner used to say, "Never Mind."
