On the fuel rail, which is the inlet port. The 5/16's line or the 3/8's?

I believe it's the rearward, then it returns after the FPR.

Okay cool, thanks

I don't/didn't know they are a different size. Me thinks they are the same.

I have a 92 rail and the right port is 3/8 while the left is 5/16. The smaller port is by the regulator. I'm just wanting to get my fuel lines hooked up correctly

Btw, last night I actually went out and pulled the return line from my FPR to be sure. The friggen rings stayed in there and it was a small protect to fish them out to put back on the line to put it back right.

No complaint! Learnen every day here.
