how important is fuel pressure safety switch
You could live without and may never have a problem. It is however very cheap insurance if something happens with your fuel supply. Not familiar with the NOS product numbers but I'm assuming that's a wet kit.

Meh. I don't use no stinkin' FPSS... Then again, my thinking is that if I blow the motor, I'll be forced to build a forged one. Seriously, I read many threads about FPSS giving folks issues, so I skipped it. I guess any extra safety is a good thing, but IMO not totally necessary.

A fuel pressure safety switch is cheap and can save from a bad weekend. If you have a small shot and good way to monitor whats going on, its not as important but it can never hurt.

So if the fuel pressure drops, the FPSS will shut off the nitrous correct?
What happens if your fuel noid sticks shut, will it shut off the nitrous? You still have fuel pressure if the fuel noid sticks shut correct? And all that nitrous going into your engine by itself?

Your FPSS when wired properly will cut power to both noids. However if you have a noid issue, nothing will help you. That's why it's always wise to crack your bottle before hooking it up. Clear all the lines on a regular basis, etc. Beyond that if junk gets in your solenoids somethings gonna give.

Is there any thing you can do prevent objects from getting inside of your noids? I don't really see how anything could get into them but I have heard stories.
-What do you mean 'crack the bottle open before you hook it up?'
-When you say you should clear the lines, what do you mean and how often? There might be months when I go without spraying. Should I clean the lines by purging every once in a while? How often, how long?
-What goes wrong with the FPSS? How can you hook it up wrong?
-What problems?

DERTY: So the FPSS is only worth while if your fuel system goes out and pressure drops then, correct? Not if your fuel solenoid sticks shut because there IS fuel pressure...the FPSS won't do anything.
