Is this the correct way the fuel should flow? This is what makes the most sense to me but I've been staring at the FSM and the diagrams on courtesyparts. From the looks of it the fuel doesn't go this way stock, am I crazy? :crazy:

Tank Feed --> Filter --> Pressure Regulator --> Rail --> Return to tank

Can you guys confirm how the fuel should flow?

Yea that's what I thought from the diagrams but it seemed to me more logical that the FPR would be before the rail.

Is the setup the same when using an adjustable FPR?

I've also been trying to figure confirm that bottom barb on my OBX FPR is the in and the side is out.
