I ordered a digital fuel pressure gauge like you put in a dash or a pod that comes with 9 feet of line between the sensor and the gauge. Im going to wire a 12volt cig lighter plug to it when it gets here.

With this I should be able to tap the fuel line for a reading and drive the car and watch the fuel pressure.

I have been meaning to do this for awhile. I had a Bluetooth one years ago but cant find it. But with this rig I can test the problem I am having on the new x5 and a problem one of my pickup trucks is having too so it will be handy to have.

It gets here Thursday so after that I can rule out the pump, pickup screen and filter at least.
