Is there a way to test the fuel pressure regulator..to find out if its on the way out. Reason is I've been experiencing a sudden drop by 1-2 litres per km in consumption. Especially after a TME tune, new spark plugs,new o2 and new ICE leads I was expecting an improvement from the usual 9km/1L I was getting..instead I'm getting 7-8km/1L now. Driving and use of A/C has been conservative of course.
I did a bit of search online and one method was to have the car running and then disconnecting the vacuum hose from the regulator and see if fuel would start dripping from the regulator after 5mins.
another method was to attach a hose with a meter reading psi and see what psi its reading with and without the vacuum hose. problem is I'm not exactly sure where to attach the hose with the meter..:blush:
Also would anyone know the MD part number of the fuel pressure regulator and whether or not an Evo9 fuel pressure regulator is a direct bolt on replacement for our cars.
thanks in advance.
