I got the number for the WIX filters technical hot line off the web (800 949
6698), I couldn't find a number for Fram but I'm still working on it.
WIX says that their replacement for the PH8A (WIX # 51515) indeed does have
a bypass built into the filter and its activation pressure is 8-11 PSI. WIX
claims that many of their other filters do have bypasses but filters
intended to be used with an adaptor with a bypass delete this feature.
Are we convinced yet?
BTW, I'll find out if that renault filter has a bypass because if it does
not that could be bad if you use it on a Ford small block.
