MANN FILTER has published a document explaining the differences between fuel filter PU 8014 and PU 8021.
On the document, MANN FILTER said: “On some VAG 1.6/2.0 TDi applications, two original equipment fuel filter housings are installed, sourced from different suppliers.
“The integral filter elements from each supplier differ visibly too and this may cause installer concern when selecting a replacement filter.”
Water drain device
When selecting the correct replacement filter, the first step is to identify if the original filter housing has a water drain device.
The water drain pipe, if fitted, can be found at the top of the filter housing.
MANN-FILTER added: “PU 8021 and the alternative supplier’s filter element differ dimensionally, due to patented design factors.
“Positive installation and performance of PU 8021 is assured when installed into either OE housing.”
