Hello all, I recently installed a stage 2 water meth kit it all went together as expected. I just have a coupe concerns. I'm running the nozzle post TB and am worried about siphoning the line, I have a 20psi check valve but I dont think it is enough to stop vacuum from pulling it open. So I bought a solenoid and was told to install it between the tank and pump... that doesnt make sense either as whatever is in the line will be sucked out. This leads me to my question what would you all recommend for solenoid placement? I also cannot get a straight answer on nozzle sizing from the manufacturer the instructions in the kit state something totally different then what they have online. Current mods are, Injen SRI,Isr O2 housing Turboxs Stealthpipe Mxp catback, BTR stage A/T canned. My research leads me to the 225ml nozzle. Thoughts?
