Fueling & Injection - Fuel Rails Upgrade

I Was Wondering What Fuel Rail AND Lines I Should Get And What Are The Differences If I Go With The Cheap Ebay Ones, And Lines Fittings Etc.i Have A 408 Ironblock Ls1 With A Tnt F2 Nitrous Kit For It With Ford 42 Pound Injectors Racetronix Fuel Pump 90mm Fast Intake If That Matters.so If Anybody Has Experience With This Situation Or Whatever Please Let Me Know.

Anyone

I used Aeromotive fuel rails on my SS and wasnt pleased at all with the fit.

What Didnt Fit Right,should I Upgrade Any Fuel Lines To The Rails Also Not Sure Of What And What I Should Upgrade At The Same Time With The Rails Etc And What Sizes.

All eight of the injectors fit into the intake at sutch an angle that the body of the injector was in a bind angainst the intake.

i have used both the speed fuel rails and i am currently running the FAST rails now, havent had a problem with either set and they both come with kits..

Could always use NastyPerformance rails;)

Nate

I got the Nasty Rails.... Looks good and fit perfectly!

Once you get the rails what did you do for a regulator?? Doesnt it get removed with the factory rails?

If I am not mistaken, the regulators are in the tank for teh F-bodys. The vettes have it on the rails.

I did have to put an after market regulator due to seeing 70 psi on the rails after the rails swap. Before it was 63psi which was too high any how. So, in my case, the regulator was not working.
Here is how I mounted the regultor and originally spliced it in to the stock return line back by the "T" by the fuel filter..

But, it was not regulating at all when adjusting the screw. So, I called aeromotive, they said to disconnect the line where I spliced it in and run it into a bucket whith the car running and see if I can adjust the regulator, and well, i could adjust it no problem.. So, where I spliced in the -6 hose to the stock return line, it was bottle necking it back up to the regulator..

So, I had to get a -6 to -6 fitting and run it all the way to the tank. This is how I did that portion and I can regulator the fuel pressure with a twist of a screw now.. I did it this route as I did not want to drop the tank. Once I put the cut out porttion back on and throw the carpet down, you cant even tell..

Do you have a parts list for the fuel line conversion? I wouldn't mind just running - 6 line from the pump to the rails.

Youll be fine using the stock line from the pump to the rail (unless you are puttin down some serious HP)... I had to use -6 line from the rails/regulator back to the pump as it could not drain fast enough thru the stock line. I bought the nasty rail kit which came with the -6 with a quick connect and the rails with the -6 cross over line as well..

I did not have problem from the tank to the rail, I had a problem from the rail/regulator to the tank. Is that what yo meant?

I think so... I am currently trying to figure out how I need to configure this system because I have a supply and return line. For some reason until tonight this totally slipped my mind, and now I am trying to figure out what exactly I need to buy in order to install this setup.

I want to do a direct mount fuel pressure gauge so I was looking at the FAST part# 54028G-KIT which claims to be the LS1 installation kit with the pressure gauge, but what do I do with my return line since I don't see it taken into account here?

Any help would be great.

I will try to get into contact with Nasty to see if he has a kit for me. From what I understand those guys are great.

Yea, Nate at Nasty is awesome... He lent me some rails so I would not miss my dyno/track date.. And when I got mine, I installed them and sent his back.. Cool guy for doing that.

What exactly is the problem? You just want to read some fuel pressure on the rail?

Are you wanting new rails for the bling bling?

I had to get new rails cause I broke my stock fuel rails.. So, I just upgraded.

I figured since I was upgrading the intake for future mods (ATI Procharger) that the rails would be a good idea as well; however, I fear my research has not been all that great in the fuel department. So getting these new rails is a learning experience for me, and is sucks not having a write-up for help.

Yea, these rails with the braided lines will look pretty tight with a procharger and the polished plenum under the hood...

Just start with the nasty rails... It comes as a kit. It comes with all fittings, rails and hose, hardware. I added the rest which is from the passenger side rail on. Its going to come in pieces so you are going to have to cut the -6 line to lenght and put the fittings on.

Maybe Nate will cut to lenght for ya so you just have to unbolt the old rails and bolt the new ones on, thats up to him though.

So putting together the -6 line with the fittings doesn't require a tool? For some reason I thought it did, but the fittings also look pretty self explanatory as well.

Nate helped me out. Thanks for all the info!

Cool... Nate is a cool ass guy! He helped me out alot!

the low buck way is to use some Mustang fuel rails backwards they are the same spacing for the injectors. All you have to do if fab some mounting brackets for them

what is that air filter setup you have there?

It is the Suncoast Creations intake for their hoods.

looks like one for a lt1 car

looks like one for a lt1 car


Because you have to replace the LS1 Radiator support with the LT1 setup.

so it is for an lt1?

The intake will work for both I believe. I know for a fact it works on my LS1.

Yep, extreme is corerct. The hood closes right down on the filter. Works pretty good and IMO, better then the stock style set up.

SEBLS1, you mailbox is full....

I can't tell from the pics. Are Nate's rails pipe thread or "O" Ring.

Not sure what you mean?

One of these two types of fittings would go into the end of the fuel rail.


O-Ring

Pipe Thread or NPT, this sample is a reducer

I am a little confused by this image. Where is this steel braided line going to?

Engine bay looks very nice BTW! :)

I know it wasnt the O-ring type, but I am just havin a brain fart here.

Maybe PM Nate and ask him.

That be the return line coming from the regulator...

I originally spliced it into the "T" back where the fuel filter is but I could not regulate at all.. So, I called Aeromotive and talk with Jared. I described my set up and issues, he told to me pop the line off and just drain into a bucket instead of the tank.. Did that, started the car and I could adjust my fuel pressure no problem.. So, I had to run the -6 line all the way into the tank for the return as where I had it spliced into the factory line, it was choking it up.

So that braided line you see is the return coming from the motor. I capped off the fatory return line.

They're NPT. I says it on his Website. Shoulda looked there to begin with LOL
