Champion rails with aftermarket lines

[TT/Ameasap]

What are you guys running for lines with your champion fuel rails?
I have champion fuel rails and want to run -10 feed -8 return, but need ideas on how to get -10 to billet FPR?

It just seems like a bottleneck to reduce the size.

You can use a reducer fitting from the line to the regulator

Ya, I know that, but I was concerned about flow restriction. Or will this be ok?

The Champ rails are -8 AN if I remember correct, you are saying the FPR you have is -10AN in?
FWIW...I run -10 feed split to -8's right before champ rails....then exit rails w/ -8's to FPR, works fantastic.

 

[TT/Ameasap]

The biggest FPR fittings I could find is -8AN inlet and outlet. Thats what I was looking for. This is the Fuelab FPR.
I am getting rid of the restrictive stock style billet FPR and running short Champion Rails. This will help with having a larger return.
So I will have -10 line from tank to -10 Fuel pump to -10 fuel filter and -10 all the way to rails, -8 fuel rails, then from -8 fuel rails to -8 FPR to -8 Return all the way back to tank.

If I am understanding you correctly, your FPR has -10 inlets, if that's the case here's what it sounds like you need...(2) of these selecting -8 Flare to -10 O-ring:

Well, i was going with the stock style FPR and decided to go with the fuelab FPR which is -8 in -8 out with the short -8 Champion rails. Problem with the stock FPR is the return restriction......My feed line is -10 going to the PS fuel rail...Which will have to reduce to -8 for the champion rail.
Is that clear as mud?lol

 

[Firechaser]

Your setup should work just fine, it may be a bit easier for you to split the -10 feed under the car w/ a Y Block...then dual -8's exiting from the Y Block into the Champ rails...just from a room perspective, the -8 lines are more friendly and in theory should keep the pressure up w/ the reduction. I have mine done this way w/ a Weldon 2035 and it has plenty of fuel, my FPR is an Aeromotive fed -8 all around and it regulates just fine. Either way, you should be fed!

 

[TT/Ameasap]

Where exactly are your -8 feeds going? PS Fuel rail?

Would you happen to have a pic of this setup?

Ahhh...so, I can split the -10 line to two -8 lines with a Y block under the car and run them to the back of the fuel rails. The front of the fuel rails will hook up as seen in the pics.

 

[Firechaser]

That's funny... Pacecarta took a pic of my actual car

i would have used 45deg hose ends at back of rails , a 45 off the driver rail and 120 at the driverside to the regulator but i was trying to recycle the fittings firechaser had

the return is -8 out the bottom of regulator, hose run along side the motor mount along side of the prop valve and back to the tank

 

[TT/Ameasap]

Thanks a million guys! I wouldnt have thought of this. Thanks for the 45° tip also.

Are the Champion rails anodized on the inside? Isn't that a requirement for E85?

 

[TT/Ameasap]

They could be. I'd imagine that they are extruded aluminum to the spec size with anodized coating. Drilled and tapped on the ends. But I could be wrong. I will get a close look at mine while they are off.

I do have a hard time thinking that corrosion will occure under pressure with the liquid flowing instead of just sitting.

I an using a Y-block -10 in to dual -8's to the champ rails...-6outlets to keep the rails (loaded) to a -8 return...

check my thread with pics and vids...
