i really want to check my wrx for fuel pressure and i would like to know where to tap into for a real quick fuel pressure reading, but i have no idea where to look in these subarus. and also what kind of pressure should i be getting with a stock wrx?? thanks guys

 

to get a fp reading you need to tap off somewhere after the fuel filter and before the regulator. the only reasonable place to get it is the short piece of fuel line from the fuel filter to the hard line on the intake manifold.

 

ok so ill put a tap in that short hose then. i just thought you can pull a quick reading with a fp gauge from something like a shrader valve like fords have. thanks man
