Hey everyone, I think I have everything I need to start plumbing the fuel system for the LQ9 in my Chevelle but before I get started I have one question. I bought the corvette filter/regulator combo and for some reason im just now realizing that I have two lines coming off of the intake and only one line coming out of the regulator. So Im assuming this is for the returnless style fuel lines. From what I understand, there is an internal regulator in my fuel rail so I wont need this corvette regulator filter correct? So what kind of filter do you guys recommend? And who needs a corvette regulator/filter?

 

What year LQ9 do you have?

 

2002. It has the 3/8 and 5/16 line coming off of the intake

 

You can eliminate your regulator and use a fuel feed and return line. Or you can change to a returnless rail and keep the regulator.

 

Cool, so I can sell my reg/filter and make some extra cash. Any inline filter recommendations?

 

If you don't already have a new return line, using the vette regulator and returnless rail would be easier.

 

Why would it be easier? Wouldnt the return line go straight from the intake to the pump and the feed line would go straight back to the tank as well but with an inline filter in between?
