nitrous setup help

KBs in this build, and you're a first time "user"? Oh dear... ;)

Well, here's the way I do it. The factory 5/16 line will work, but really you should go larger. The "preferred" method for me is a rear sump on the fuel tank or cell. I run -10 from sump to filter, and filter to pump(pump in back of car...). -8 from pump to regulator, regulator to solenoid, and regulator to carb, plus the return line. Also, the regulator shipped wih the holley blue is not a return style. It's a dead head. You will need to buythe return style. Your return line should be the same size as the feed line, or your pressure readings and presures in teh system will be false high. Always free flow the NOS sytem (fuel only) into a bucket prior to running it. Set the pressure regulator with the lines and plate flowing fuel. A good way to do that is pull the float bowls, remove the floats leaving the needles and seats, and leave the lines connected. Then wire th solenoid to open and stay open. Lay the plate and the bowls in a spotlessly clean 5gal bucket, and hit the pump. Set the fuel pressure that way, then put it all back ont eh engien and you're set. Then you can jet the NOS or carb with no fear of fuel presure issues. Also, always use compressed air and I like to use brake clean to flush the newly made braided hose. Otherwise your NOS plate fuel bar will be full of debris alogn with the float bowls. Good luck.. remember, retard the timing 2° for every 100hp expected.
