This is a rubber standoff for mounting various items on Fiat and Lancia cars. Used for isolating the fuel pump and fuel filters on Fiat and Lancia cars equipped with fuel injection, and also used for power window regulators.
These quality aftermarket replacements are sturdier than the originals, 15mm thick rubber pad with the correct M6x1.0 threads.
Good for quieting aftermarket electric low pressure fuel pumps as well.
New and unused.
