I already know what you're thinking.
So, they might be purple, but they fit.
They are even more glowing in person.

yep i've had a set of them on my truck the whole season. i helped design them. and if you look at mm & ff a few month back in the 1st few pages you'll see them on my motor in the pic
this is what they looked like in november of 2001


and this is the 1st prototype set ever made hehe (i got them free)

 

www.cprracing.com they also have a killer fuel pump and filters in the same purple anodizing that looks to cool to put under the truck look for them to be at a tuner near you in a few weeks

 

calightnin, did you also upgrade the lines to the fuel tank? Were the stock fuel rails not big enough for the 580+ your truck is putting out?

 

He tried everything in the world (including spending lots of time on the phone with CPR), but their rails just didn't fit. He's running a set of Works prototype rails right now.

 

I ended up not using those rails. They did not fit over the coils on to the injectors well (hit the top of coils before they could seat down over the o-rings on the injectors). Also the tabs that hold the rails to the intake were poorly welded, and did not line up to the holes on the intake. Also their customer support was less than desirable. They said that they had trouble with their welder. They also said maybe I got a set of 4.6 rails with Lightning tabs welded on it. They were to send me another corrected set within a week. That has been since the beginning of December. I gave up.

I ended up using a set of rails made for me by Chris At Works Power.

I also used a CPR fuel regulator and it had leak back, so I switched to an Aeromotive regulator.

My fuel lines are all now -10 braided. I do not know if it was necessary. I did it as a preemptive strike against the issue in the future.

PS: easterisland: I upgraded the lines thru and into the fuel tank.

i'm not going to make excuses for cpr but they are local (a mile away)
well some of the issues have been resolved w/ the fit along w/ the mounting tabs. they have had my intake for a month now and all the rails from here on out should have no issues. i have the original set of rails on my truck since last march. they do now have fittings that allow the use of the fuel rails on the stock fuel lines so you wont have to upgrade the whole fuel system at the same time.

 

Another question is if the fuel rails are too small the supply line is also probably too small. Why shouldn't someone upgrade the entire system at once? Maybe there is something I'm missing.

I'm just trying to get things in line for the KB and some nitrous. I'm guessing I should hit the 500+ hp...

 

i'm running a fuel cell w/ 8 an lines w/ cpr rails regulator and pump. did i have to well not really. but all i had to pay for was the fuel cell and lines so why not.

leornard,

i would say if your going that route upgrade the whole system but this is just an option for the guys that are looking for that look or the option of adjustable regulator and dont want to or can only do a little at a time. but the rails are 9/16 through holes which are larger (read more fuel cap. than aeromotive). and yes the set that calightning got was one of the 1st batch of rails that got out. and due to his calls cpr has borrowed my intake and has redesigned the mounting brackets and the clearance for the coil packs. and will soon be offering a kit to boltup to the stock fuel lines for those like i said want to build up to the complete system a step at a time.

 

I emailed CPR and they had the following prices
fuel rails $299
adapter for stock fuel lines $59
adj. pressure regulator $139

I won't do the fuel lines unless I do from the inside of the tank forward.
