been lookin and looking and cant find a definitive answer i have a wally 255 and a fuel lab afpr it has 2 inlets on the sides and one outlet coming out of the bottom, i have the line coming from my fuel rail on the right side and my plan was to tap into the inlet on the left side, does this sound right??? i've seen people saying to tap into where the gauge goes but i already bought the -6an threaded adapter and i would rather use that than the 1/8 hole?? and if my thoughts are right both inlets should share the same channel in the fuel lab afpr and have the same pressure at them as my fuel rail? sorry if im making this confusing also im running a wet kit and only about a 50 shot for now
 
yea, you're right on track with your thoughts.... I run my nitrouse off the port on the opposite side of the gauge, the fuel comes in at a 90* on the other port. My AFPR is aeromotive and has 4 ports (one on each side of the square unit, with the outlet on the bottom.) I've been running my nitrous like this for a while now with no issues on asingle nozzle fogger, and on my buddies 4 port system as well and we've never had issues.

JUst when you hook it up, have the bottle closed, arm the system and lay into it.. you should hear the solenoids click and see the AFR's go dead rich. if that happens then you know you're most likely safe ot open the bottle and throw laughing gas in the mix as well

and just to be safe i'll mention the few cardinal rules on n2O... well relaly just one.. make sure you have some way to keep it from coming on too early in the RPM range.. On V8's the rule of thumb i learned was NEVER spray at under 2500 RPM because you can bend a rod. ON my little four banger 4g63 i don't let m,ine come on untill after 3500, the the turbo is in insta-spoool and i'm burning rubber in third like i had dumped the cluthc in first with a pegleg diff LOL :D me love the laughing gas
 
thanx man i had nitrous on my 83 cuttlass with a 355 chevy i would just wait till i slammed 2nd and about when it would want to stop spinning i would hit the nitrous on LOL
