Yes. WK 853/3 X replaces 1J0 127 401 A as well as 1J0 127 401, 1J0 127 401 B, 1C0 127 401 and 2D0 127 399, with the same 80 mm body and 8 mm ports.

WK 853/3 X fits VW Beetle 1999 to 2006, Golf Mk4 2000 to 2006, Jetta and Bora 2000 to 2005, Passat B5 2004 to 2005, and Audi A3, A4 and A6 1.9 TDI.

WK 853/3 X is rated 30 micron, with an 8 mm inlet and outlet and a 177 mm body height.

The check valve keeps fuel in the supply line after shutdown, so the TDI engine primes on the first crank instead of drawing air through the filter.
