View Full Version : **HELP with finishing RB20 swap**

02-14-2012, 06:38 PM
Need help with finishing up my RB20 swap in my 89 Sohc.


I believe 1 is the FPR vacuum? 2 is the aftermarket FPR? 3 is a line from the Fuel Rail?

If 2 is the FPR where do I hook up the line for the FPR vacuum 1? Which goes to the fuel return lines? And which goes to the fuel filter?


Here are different angles.


This is on the firewall side of the number 3.


Is this all the wires I need for the dash wiring? This is what came with my harness for the RB.


This is from my 89 sohc Dash wires. Any of the other wires useful?


And last my car was originally auto...Can I leave them like that or do they need to be plugged up atleast? I didn't do the reverse lights yet, plan to when I get the actual car running. Already did the start up/parked plug can't see it though.

Thanks for any help!

#1 is a vacuum source for whatever, sure FPR go for it

#2 is just a fitting, you have no FPR on that rail. That fitting is used in conjunction with aftermarket regulator and or gauge

#3 is, or should be, the feed line for the fuel rail. You will run the fuel line from the fuel filter into this.

Okay thanks, I get #3. How about the other fuel line? The lower one right next to the line that connects to the fuel filter. Where do I connect that?

And so I have no fpr? What should I do with #2?
