Weber DCOE Pair of Vacuum Inlet Pipe Banjo Fittings – M5 Thread
These vacuum inlet pipe banjo fittings provide a threaded connection between a Weber DCOE carburetor and a vacuum hose or vacuum takeoff circuit. They are used at the carburetor’s vacuum port to route a controlled manifold signal for an applicable gauge, control device, or other vacuum-operated system.
The fittings combine an M5 threaded carburetor-side interface with a hose connection. A secure, correctly sealed connection is important because an open or damaged vacuum port can introduce an air leak, weaken the vacuum signal, and contribute to unstable idle, inconsistent progression, or inaccurate tuning readings.

Correct geometry and sealing interface remain important during service. Confirm that the hose fits the visible outlet section securely and that the fitting seats correctly in the carburetor without forcing the thread. MPN ST2578.

Important Fitment Note
Verify the carburetor family as Weber DCOE and compare the required vacuum-port arrangement with these fittings before purchase. Check the code or marking on the carburetor and compare the M5 threaded section, outlet geometry, sealing interface, and hose connection with the removed fitting. Also confirm that the replacement seats at the same depth and orientation without thread or clearance interference.
Compare the removed fitting carefully; M5 thread alone does not confirm complete fitment.Show all parts
