FPSS Location I have a NX FPSS and it says to install it directy into the N20 solenoid. I was wondering if I could just mount in on the end of my fuel rail as space is a little limited around the solenoids. Is this cool or bad idea?

i dont know why you wouldnt want it as close to the fuel noid as possible to assure adequate flow throughout the system instead of just by the pump or before the regulator
thats like getting false readings. put it right at the fuel rail is the norm.

"The best location for fpss is at the outlet side of the of the fuel pump...This location will allow instantaneous n2o sys shutdown is case of fuel pump failure. The next best location would be on the high-press side of the fuel press regulator...

But no matter a low pressure system is not applicable in this case anyway.
