Product details
The PMO PM-O111-0 is the top cover gasket for PMO Induction carburetors, sealing the joint between the carburetor body and the top cover. EMPI lists it for all PMO carburetors, so one part number covers the 40mm, 46mm, and 50mm carbs. The top cover comes off for float and needle valve service, and a gasket that has been compressed, torn, or swollen by fuel should be replaced when it goes back on. It is priced each, and each carburetor takes one.
PMO's rebuild kit parts sheet lists PM-O111-0 as the "Throttle Body Gasket," two per kit, one for each carb in a set. The 40mm, 46mm, and 50mm rebuild kits (PM-O700-0, PM-O700-1, and PM-O700-2) also include needle valves, float shims, and accelerator pump parts. PMO states that the gaskets, diaphragms, and seals in its carburetors are E85 compatible.

Fitment & Compatibility
Fits all PMO Induction carburetors, made in 40mm, 46mm, and 50mm sizes for air-cooled flat-six Porsche engines from 1965–1998, such as the 911 and 914-6. Weber IDA carbs are not among its applications.
Installation & Tuning Notes
Clean both sealing faces before fitting the new gasket and tighten the top cover screws evenly. After reassembly, check the fuel level in the PMO sight glass, which reads without taking the carb apart.
Common Questions
Is the throttle body gasket in the rebuild kit the same part?
Yes. PMO's kit sheet lists PM-O111-0 under that name, two per kit.
How many do I need for a 911?
One per carburetor, so two for a typical pair of PMO carbs.
PMB Performance stocks PMO service parts and can help you plan a rebuild.
