1987 325iC fuel lines... Which is which?

[E30SRPower]

Hey guys. PLain and simple. I should have written it down. I guess it just slipped my mind. There are 3 fuel lines that come up the inside of the driver's side frame/unibody rail. They are arranged vertically where they change into rubber lines at the firewall.

I need to know which is which to finish my engine install. I traced the lowest one to the fuel pump output. I believe the highest one is the vent, making the middle one the return line from the FPR. This will take only moments for someone to look at on any "i" series E30... PLease confirm this for me so I can get my car running.

thanks guys,

Does that help at all?

No. But I guess it is the thought that counts.

Anyone with an i egninge should be able to trace the fuel lines in like 3 or 4 minutes. can't anyone do that for me?
