Question, Had my LS3 intake & TB ported on my 01 C5Z. While everything was off I purchased the Holley LS Fuel Rails without the hose and fittings because I get AN Fittings and Stainless line cheaper from a vendor I work with... I am ready to install the intake and order up the fittings I need ect. My question is as simple as a task this is I was wondering what fittings you guys have used for a simple easy fit. I plan on running 2 -8 90* Elbows with a -8 crossover line in the front, Plugging the driver side rear and running a -8 90* elbow on the passenger rear and going with -8 braided line running around the back of the intake "Firewall" to the OEM stainless flared line. I was going to hook this up with a Aeromotive 15118 connector which pushes on like the factory line with a AN fitting female on the opposite side.

Basically look similar to this but with a 90* Elbow hooking from the Passenger rear towards the driver side...


Now is this seem like a logical way to run this? or will I encounter issues with room in the rear? Also would it be more beneficial to just block off both rails at the end and Run my crossover in the front with a T on the driver side and run that directly to the hardline?... OR should I do a crossover in the rear "IF ROOM" and plug the passenger side front and run a AN U Elbow off the driver side front rail going back to the hardline.. Something so easy but so annoying hahaha... Thanks for any pointers... This is a returnless fuel setup FYI

I don't run a Fast, but my MSD intake did not have enough room
in the rear for a cross over. I ran mine on the front. Good luck.

You wont be able to run a crossover in the rear unless you do some cutting.I run mine through the front

Sorry for the thread revival, but hey at least it is still from 2016. Haha. Had a similar question. Why does the original picture from Hinson show the driver's side rear plugged and the line from the rear passenger rail wrapped around back to the factory hardline?

Any reason they don't plug the passenger rear and just run from the rear driver's side to the factory line? Too tight to make the connection?

Clearance, it's almost impossible to run on driver side because the firewall is so close...

Thank you. I did some more searches on the forum and that was the conclusion I found as well. What route did you end up going with? I just received my Holley Efi rails and thinking about the install myself. Planning to do similar as pictured in your original post, but just now realize I don't have a 45 or 180 degree fittings for the line behind the intake.

I ended up going the same way shown in the Pic above... I ran 2 -8 90* with a crossover up front and plugged the driver side rear. Ran a -6 45* pointing @ 4-5 o'clock if you were looking at the motor from the front. Looped that behind the intake and did a 180* fitted into a AN compression fitting that fits on the flared hard line...

That is a very nice and clean pcv routing. I wanted to do something similar but hesitated and now seeing your pics made up my mind. Nice job by the way. I am going to use braided lines for mine though.

Thanks man, mine will be changed to braided as well... I did the rubber to get it tuned.. "had a PCV Vac leak originally with my old catch can/breather configuration"...

here is how I have mine..

Thanks, hey how do you have your pvc routed? I have 2 -10an going into a catch can but that bitch is spraying oil all over the place. Its a crappy catch can with a filter on it. Not sure what I was thinking when I did it
