Quick question... which number is inlet, and which one is return line? Installing a FPR and need to know which like to slaughter... I could find this myself but dont really have the time right now to climb under my car. Thanks in advance. BTW line #1 is coming from the driver side (USDM) and #2 goes under/ down the firewall around the center

 

Simple way to make sure you have the right line. Unhook them both, and place a bottle/can under each, and turn on the pump. The one that flows fuel into the container is the supply.

 

well i cant right now, thats why i was asking if anyone knew off hand. im gonna do it tomarrow but ill be in somewhat of a hurry.

 

You're going to have to unhook them both anyways. Do you really want to take a chance on someone giving you the wrong info, and having to redo the system?
With the vague description of the locations, it would be a guess to say which is which........

 

hmm .. funny how some people are ... no offence but in the time that you took the picture, came inside turned the computer on uploaded the image, went on the rx7club website and wrote this message you could of found out yourself ...

 

I am going to take a chance and say 2. The clamp looks a little larger diameter, but 1 looks more pinched so it is a tough call. The supply line is bigger than the return if that helps.

The line closer to the driver side at the firewall is the inlet, and like T_racer says, is thicker. So #1 is inlet and #2 return.

BTW, lazy bastard
