I pick my kit up tomorrow and was wondering about hooking up the fuel line. As it sits right now I have a Walbro 255 pump, Sard 720cc injectors, and an AEM afpr. The afpr has two inlet ports and a port for the fuel gauge. One of the inlets is coming off the rail and I have the other blocked off. Would it be possible to use the other inlet for the fuel solenoid or t off of the fuel pressure gauge? Will this take too much pressure away from the injectors? Keep in mind that I'm only using the nitrous to spool the turbo and once the turbo is spooled the bottle shuts off. Any thoughts are appreciated as always.

tee in after the filter is fine; since it's always pressurized, it should be fine.

Please be careful with NOS. Every single person I have ever known that has sprayed has blown their motor. Let me list...

1x B18c Integra (GSR)3x D16 Civics (SOHC VTEC)1x KA24DE-T S141x 2JZ-GTE S141x LS1 WS6 Firebird

NOS is the devil!

You are talking about tapping into the fuel line, so I assume you are going to run a wet kit. The ONLY way to ensure proper distribution of NOS/Fuel to each cylinder is using 1 nozzle per runner on your intake manifold. Having said this, I know for a fact that you cannot run a 50 shot with 6 nozzles. IIRC using the smallest NOS jets & their associated fuel jets netted a 75 shot on a 4 cylinder motor.

NOS is just like a turbo. It too can blow your motor. IIRC you can set it for a 50shot single fogger setup. If he put it as close to the TB he will be ok.

75 should shoudn't be a problem IMO
