What is the consequence of using a fuel filter with a higher-spec'd bypass valve opening pressure ?
Currently have a UFI 31.833.00 / 6Q0201051C on my 2008 City Golf - rated at 4.0 bar.
Considering a HENGST H155WK02 as replacement, but it is rated at 6.4 bar.
Would this higher pressure rating cause fuel delivery issues, if the valve doesn't open until higher pressures ?
Would it just cause lessened fuel economy ?
Or is the rating just a max-permitted before the component blows-out, and have no adverse effect at all ?
