Default The Ultimate Non Fuel Rail, Fuel Rail Replacement

Tim and Corky's latest creation. It came from needing to move the fuel rail for the supercharger system that we are about to start work on. It is designed to be the best fuel delivery system out there.

It would be a whole lot cooler if you used AN lines and fittings, and not rubber hose and hose claps, dont get me wrong it still is cool.

You could always add AN lines and fittings as long as the threads matched the fittings and you used an O-Ring Boss fitting to attach them.

I was thinking the same thing. Will that hose/hose clamp combo hold at 50-60psi of fuel pressure? I'd feel much safer an AN fittings.

Very cool concept though...

Random fact of the day: OEM fuel lines are rubber with hose clamps and hold those pressures just fine.

*edit* Damn it Brain. lol

Nice piece though. Whenever you guys get around to selling the intake manifolds, I'd remove the dual feed and swap to this at the same time. Make for an neat looking and functional intake side. When is this going to be ready for sale?

I unfortunately don't know the stock miata fuel system well enough. I know that on a DSM (yes, I know, it's not a miata), stock fuel pressure is between 38 and 43psi and there are no hose-clamped hoses on the pressure side. 43psi + 20psi of boost = 63psi fuel pressure.

the stock lines had no problem when I used to run 120psi of fuel pressure. ZEX dry kit + Pierburg pump.

IIRC, Miatas run 43 psi stock and the NBs run 60ish.

On my Greddy, I was at one time running 5 psi with a 12:1 disc in my FPR. So my pressures were over 100 psi, and still no problems.

BTW - Your equation made me laugh, that's not how it works.

It does work as long as he has a 1:1 raising rate FPR like I have... But otherwise, you are correct.

Edit: Dammit, Brain beat me to it...
