Doug is correct but to be fair I remember the plumbing hell in the back and it was never entirely obvious what was flowing and in which direction it was going at the time.
I think I’m making this harder than it should be. What direction should the arrow point ? Out towards wheel or in towards centre of car?
Sorry for the late reply. The hose from the fuel tank comes from above the differential near the center of the car and connects with the end of the filter nearest the differential. The outlet hose that runs to the fuel rail in the engine bay connects to the end of the filter nearest the left rear wheel. So the arrow should point toward the wheel.
