I have a 2001 with a return line on my truck. I am putting a LS1 intake manifold on it for clearance/cleanliness reasons (show truck). I need to get some injectors and a fuel rail for it but i am not sure which to get. I want some billet rails and a braided crossover line but the kit i see for the return style vehicles has a regulator included with it. Do i need this regulator? I did not see anything like this on my truck intake. Any help would be great.

 

Your regulator is on the driver side of the intake... It has a little vac tube and looks like a small diaphragm... And yes, you need some sort of regulator for your swap.

 

You will need the regulator... I used professional products rails (can be bought on ebay) and an fittings from summit.... Speed Inc has some nice rails too that are not that expensive, they are a sponser on tech....

Here is what mine look like on a LS6 intake, I have a returnless fuel system so no regulator for me, granted I have not finished cleaning up all the wiring and misc stuff, I wanted to make sure I did not have any problems before buttoning everything up, but you get the point....

 

What injectors are you using? What does it take to run LS1 style injectors?

 

i used rails from a 97 corvette. they arent as pretty but they are return style and made for the intake.
