Description: WASO was the first supplier to Volvo of this lockable filler cap 277360. CVI had new tooling made in 2011, since when we have sold more than 3000 pcs. It fits PV444, PV544 and Amazon 120/130. It can also fit Amazon P200 station wagon though it will then leak slightly - be aware. For P220 we have now produced 277360-P220 (which comes without air outlet hole).
