What is the size of the fuel return line? I'm going to need to run an inline gauge and I found one that's a 6an. Will it work?

 

-6 AN is a little big for the factory lines. have you thought about just tapping the rail for a guage and trimming the plastic cover around it. takes a little time if your a perfectionist but looks really good. i don't have any pictures of my old setup with the guage installed but can walk you through it if you like.

 

That would be really helpful... I'm assuming I will need a tap and die set.
I would appreciate the walkthrough. Also do you know about the resitor box wiring? I've seen writeups on it, but nothing too clear on the s2k. I appreciate it thank you

 

its 5/16

 

I have a fuel rail that is already tapped if you are interested, let me know.

 

I'm intrested just let me know how much for shipping and all. What size is it tapped for? like 1/8?

 

I'm interested aswell.

 

^^^ that helps even more. and it should be 1/8"
