ok im ordering my nx fuel block tomarrow along with my fpss. im going to have my fuel pressure guage hooked up to one hole on the fuel block and my fuel line for my nitrous in the other. how many ports does the fuel block have? how can i hook up my fpss now? can i just put it inbetween my sending unit for my gauge? and also, what psi fpss do i need to get? thanks

also ive heard of people having problems with their switch because it makes the nitrous go on and off when the nitrous hits and looses fuel pressure for a second. how do i stop this from happening? i think its just where you place the fpss right? im not going to put it inbetween my fuel solonoid and fuel block cuz im pretty sure that will cause my fpss to go crazy
sorry for all the questions
