that should say "lift hook" not lift hoof. I am pulling the manifold tonight so will have that info tonight. I want to avoid teeing into any hard parts if possible, as rubber fuel lines are easy to replace.

 

So I jst yanked the upper manifold. The fuel goes from filter through PD across sec rail, down to prim. rail across to FPR and returns to tank. I planned on teeing in the rubber line between the sec rail and primarie rail. That way secondaries will get first dibs on fuel. Does this sound right to you guys?

 

im pretty sure i can answer some questions. I run a nitrous express fogger system on my 91 n/a. It's a 50 shot. Mine is switch activated so when i turn on the switch and get it to full throttle it kicks in the it shuts off when i let off. kinda sweet chicks love it.

 

That's about your easiest bet it sounds like. The best way is between the fuel rail and the regulator, but this requires an aftermarket FPR.

Ideally, if you have a big enough pump, you can plumb in ANYWHERE between the fpr and the fuel pump. As long as you see a constant fuel pressure.

One idea for tuning that you may wanna consider: a fuel pressure gauge. Rail pressure increases as boost increases, so you have to tune your fuel jetting accordingly. IE: You need to tune for a rail pressure of approximately 46-47 psi if you are hitting the button at full boost.

As for the person who mentioned 8-10 inches... Too much. Its just overkill. 3-4 inches is all that's needed. There's no harm in 8-10", but no need or benefit either. Keep in mind NOS's new "Topshot" system, which mounts on top of carburators... maybe 2" from the the throttle plates... Interesting, no?

The Q is where exactly to plumb for fuel(on a Jspec). "chicks love it"????
