Where do you connect the fuel pressure gauge to check the fuel pressure on a 2001 BMW X5 4.4i? Is it the needle valve on the stainless steel tube on top of the engine leading to the fuel injectors?
I need to check the fuel pressure on my 2001 BMW X5 4.4i. I think it is supposed to be
between 45 - 50 psi. I do not know where to connect the fuel pressure gauge. I replaced
the fuel filter but it still will not turn over.
