Product details
The PMO fuel bar, part PM-O406-0, is a fuel inlet fitting that takes the place of the banjo bolt fittings on Weber three-barrel carburetors and is also sold for PMO carburetors on air-cooled Porsche flat-six engines. On a Weber IDA, fuel enters through banjo fittings on the carburetor top. PMO describes the Weber banjo setup as highly prone to leakage and limited in capacity on high-flow engines. Its own carburetors use a redesigned fuel inlet that PMO says delivers a higher, more balanced flow rate with leak-free delivery compared with the OE banjo bolt arrangement.
On a 911 the carburetors sit on top of the engine, so a seeping banjo drips fuel onto hot engine parts and needs fixing promptly. Owners usually order fuel bars when new sealing washers no longer stop a leak, or during a carburetor rebuild. Check fuel pressure once the system is back together. PMO's fuel pressure control units, PM-O403-0 with barbed fittings and PM-O404-0 with AN-6 fittings, are specified for carbureted engines.

Common Questions
Why replace the banjos instead of just the washers?
New washers can stop a seep for a while. The fuel bar replaces the banjo fitting itself, so the joint that kept leaking is gone.
Do I need a fuel pressure regulator too?
If your system has no way to control pressure, yes. A new inlet will not fix a pump that runs too high, and PMO offers control units for carbureted engines.
