My stock LS3 fuel rail has supported 937+whp on E85, but I have to imagine I'm at the limit

What aftermarket rails are people running?

Do they clear the firewall without any issue?

I'm looking to run a -8AN to the rear of the passenger rail, -8AN cross the front, then -6AN out the back of the driver rail to my regulator. The only part that seems complicated is the fittings at the rear of the rails if space is tight and the rails aren't the correct length.

I run the Holley Rails on a stock LS3 manifold.

Wow... that seems like a great bargain option

Did you upgrade the oring adapters from -6 to -8?

Could you run a 90* full size fitting off the back, or did you go with something else?

lt1z

I am not running a return system but I don't see why you couldn't run a 90.

Just thinking from a space standpoint. Some rails need a banjo type fitting vs. 90* on the back since the firewall is so close

RSI rails but I had Dallas Performance ones for awhile and they were much nicer and would do those if I had to change. I was dumb for selling them.

Nasty nate rails are suppose to be nice too.

My Aeromotive rails fit my LS7 application perfect.

Dallas Performance actually said they don't sell them anymore. Only available for local install on site.

Got the nasty nate rails, they are solid and seem really nice piece.

Did you use the -8 banjo type fittings they sell?

turbotuner20v

Any pics of them or what the kit came with? How's the line run to/from the rear of the rails? I like the black option.

The only banjo fitting I can find is a -06AN to a -08AN. Is that what you used?

So I'd need to reduce to -06AN... does that impact flow enough to limit the improvement of going w/ an aftermarket set of rails?

DSteck

Nope. Standard -10 orb to -8 AN.

turbotuner20v

so you just connected to the straight orb w/ a standard 90*?


not having a motor in my car right now is hurting my ability to see how much space is where...

Do not, I repeat do not buy fast fuel rails. I could not keep the things on, now I have a set of aeromotive rails and so far so good.

Dallas Performance put Aeromotive on mine.

I have aeromotive and they fit great but I have to give them up. they may not fit on the allpro intake

Jeff I just bought the Dallas performance rails just before TI?? But anyways I will tell you they are made exactly like the Wilson Billet rails very nice. I used a O-ring 90 hose end so I didn't have to modify the fire wall and didnt have a hard 90 because I don't like the presure drop you get from hard or machined 90's not to say it won't work fine, because a lot of ppl use them with out issue its just my over engineering mentality. I have several sets that I own and have used so if you want to chat give me a ring. Or you can just pick up what you want. GL!

Nice, I never realized those o-ring 90* AN fittings existed

I'm pretty sure the fuel line had a 90* hose end.
