There are two fuel lines connecting the fuel injection system to the pump/tank
at the rear of the car. One is flow and one is return. For this purpose, it
doesn't matter which is which. Follow them both to the side of the metering
head. If one doesn't go there, just follow the other. If the bolt securing
the line to the side of the head has a hexagonal head - you have one of these
filters installed. If the bolt has a round head with a 10mm Allen socket in it
- you don't.
So far, this test has been conclusive.
