Does anyone have knowledge of where the orings are in the fuel system. The problem has finally gotten bad enough that I can tell its going lean with the wideband and more importantly the car is running worse after changing the fuel filter which wouldn't make any sense except I noticed the oring on the filter was not looking to good but figured I'd re use it and check for leaks. There are no visual leaks but before I replaced the filter the system was atleast somewhat holding pressure and now its not holding pressure.
