UMS 7-90cc INLET PIPE WITH VACCUM PIPE-2 ( X 4 PACK)

This is the inlet pipe with vaccum pipe-2 for the UMS 7-90cc engine, the seven-cylinder 90cc four-stroke radial from UMS.

The part itself is the inlet pipe with its number 2 vacuum take-off pipe fitted.

Why it is replaced: a matched assembly for the second take-off position, renewed when the pipe joint leaks. Supplied as a pack of 4, which is how these small parts are normally bought — you rarely need just one.

Fitting note: Check for leaks at the joint with the engine running.
