I have a NOS 5177 kit and I'm contemplating not even using the fpss. It seems like it's a bigger headache than its worth. so do I really need to put this thing on or am I safe without it?

Safer with it, but NO its not requirement.

Safe is better then sorry. But I never ran one

That is like saying a condom is too much work, I will just pull out. You might be safe, by why the hell chance it?

Cause it feels so much better!! lol

Quite a few run without them--I say if it makes you feel better, then use it. FWIW, I don't run one, and I've been fine so far.

they are not needed, but 99% of problems reported by them are people who don't have enough fuel setup, to eliminate the short lean spike when the kit hits

Is it as much of a headache as installing a new motor???

Install it where it belongs. In the trash. The switch I had would cycle on and off with engine vibration, and it went in the trash.

Well SS it's definetly not as much of a headache as viewing your non-insiteful response. I just wanted to get everyones opinion on the subject, not a smart-*** answer. So if anyone else has any input, it would be greatly appreciated. How many people here use them? How many don't? Thnaks guys.

Yeah, I have had problems with mine. I even tried to tweak it a bit and it still surged on me Screw em. Just make sure you have a good fuel system.

cheap insurance, and youve got it already right? might as well put it on....

This is the type of question where you will get a 50/50 response. Technically NOS and NX recommend it, however a great number of people have had issues with them. It's cheap technology and sometimes doesn't hold up well. It can be flaky for some and just as risky if you wire it up.

For instance, if the unit is flaky and it starts toggling your fuel on and off, or if your kit kicks on and off (wire the fuel and solenoids through the switch off a relay) you will have some heartache to deal with.

Personally I do not use them. I rely on good working equipment and a good eye on the gauges. I've seen others put it into their system and notice that they basically screwed both wires together to short circuit them. And others run them with no issues. In your case if you wire it in and it works, great. If not, try something else out. Let us know how it goes.

I had issues with mine, till I adjusted it. Install it for piece of mind.
The one time you spray and your fuel pump dies, you are going to wish you had one.

I have all the safety devices, and have been running N20 for 2 years with no problems yet. <knocking wood>

How did you adjust yours? You have a fuel pressure regulator? I to have mine shorted for now as it doesn't work properly..

I don't use one on my wet kit. Just get a good tune and have a pressure gauge if you are worried. If I blow my motor, it will give me an excuse to build a better one...

What is a FPSS? Thanks , im considering nitrous b/c i have and offer for a NX wet kit off my friends Impala SS for 300 and he bought it new like 6 months ago for $6-700 so im thinking of buying it and spraying a 100 shot just so i dont have to worry about anything. But i have an M6 so im researching the best way to do this.

Fuel pressure safety switch or otherwise known as a Hobbs switch. Basically it's a normally open electrical contact that is closed with X psi of fuel pressure. You use that contact to a relay so that you can disarm your nitrous if the fuel pressure goes below the predetermined pressure (X).

I wish I had a quarter for ever time I've seen posts questioning the use of a FPSS. LOL
