Aftermarket Fuel Rails?
 

Hey can anyone give me some direction on where to get some good aftermarket fuel rails for a decent price.....

Any help would be great thanks

If anyone knows of a good place to pick up -AN fittings for great price let me know that too!

I don't know about aftermarket pre-manufactured fuel rails, I know you can buy fuel rail and a special drill bit and make your own.

The stock s5 fuel rail is pretty good.

Be careful of Stainless steel lines. If properly installed, they are Ok, but they have a nasty tendency to spring leaks at very inopportune times.

I have an S4 I know there are some aftermarket fuel rails you can buy I could buy aluminum and drill injector holes but I dont have anything to tap to put the fittings in... Im going -AN....

I usually buy the bungs and TIG them on. Makes for tighter fitting fittings. Any machine shop will be able to tap them. I would be worried about drilling holes for injectors though. Without a proper bit/polishing of the bore, you're likely to tear and o-ring or have the potnetial for leaks

I've made my own and used a few different aftermarket rails. If you haven't made them before just buy them pre-made and save yourself some headaches.

Summit and Jegs are hard to beat on their -AN prices. Their house brands are less expensive but I have had issues with the Summit brand leaking. I'll usually pay the markup and stick with Earl's because I know I'm getting a quality part.

With the S4/5 you can have the Bosch injectors setup with a pintle cap that allows them to fit in the stock manifold without the need for sleeves or a wad of o-rings to get them to seal correctly. Marren sells these injectors as their "Pro-Import" injectors at a serious markup. If you have a competent injection shop close by you can take a regular "domestic" Bosch EV1 injector and have the pintle cap changed to replicate the Denso injector for a stock fit with the stock injector grommets.

Kg rails..and Keith can make any Modifications you need to accomodate you.
I am in Canada and I deal with this Gentleman beacuse he responds quick,Knows his stuff,and his prices are good and reflect quality parts,.
His shipping/Turn around time is Real fast..Five days is VERY good for US/Canada shipping.

If you decide to make your own fuel rail, make sure you use the appropriate size ream bit. Also, radius the leading edge of the hole to allow the o-ring to squeeze in. Cratex bits work great for this, as well as the polishing Titanium mentioned.

can you not just get an fitting adaptors for the Stock S4 turbo rails? Something like 12x1.25-to-AN size and then use fittings and lines?
