Unthread the stock fuel pressure fitting port, the port where you check fuel pressure. It just unscrews, 10mm socket I think.
You can find a brass fitting, A&N type I think? Anyway you thread in that type of fitting directly into the line with a tiny bit of thread sealant. Then you just hook your braided steel line to it and then to the solenoid.
It is very easy and when I ran mine that way very safe. Everything bolted up nice and actually went back to stock nice and safely.
Two recommendations:
Bottle heater
Fuel pressure cut off solenoid ...extra forty bucks or less.
If you can do it, get the remote bottle cut off, or a secondary solenoid that you can just activate with a switch, powered by switched 12v ignition source. You should mount it near the bottle.
I advise this extra backup in case you need to manually cut off the line in case of a problem. If you shut off the car it would close the solenoid or if youhit the switch.
The only problem I ever had with my nitrous setup was the damn nitrous solenoid stuck open on my and since I only had one solenoid in line it stayed on even though I had come back to idle and the fuel had shut off. It idled high and if I had been smart enough to shut the bottle off in the trunk all would have been well. Instead I shut off the key..... BAD.
