If you are doing it off a aircompressor around 50 psi should be fine.

I along with most guys will tell you to set it in the bottom of the nearest trash can. They cause more problems then they help.

I have never ran one on the system's I have in stalled we are both at 100% hahaha

Differance is I have done 3 kits, you I think might be a few more.

The outlet nor any other profesional will tell you to remove and throw it away seeing as they need to cover there ***. I ran one for a day because it was a pain in the ***. I didn't install it on the kits I have done since. Most others will tell you to not install it also because we have had too many problems. Dave might install them but I would like to know the number of guys who throw them away.

They generaly cut in and out. It seems to be vibration triggers them or something so they think that the fuel pressure is too low. Therfore either shut the system down compleatly or as you are making a pull they will turn on and off.

Many guys have double checked fuel pressure and removed the FPSS because it was just a problem and not helping anything.

Maybe I just got a good FPSS. I have used the same one since 2003 with no issues!

They dont cut in and out unless your fuel pressure is droping to the set pressure. And in that case its doing its job. We dont suggest them to cover our ***. We suggest them to cover our customers ***.lol Truth is if you know how to adjust them correctly you will never have an issue. Thats why having a great company like us that is willing to walk you through it makes it all worth while.

I've set numerous ones in the trash can. I cant stand those things!

If you want that little bit of extra safety, 50 psi should work.

This might be a stupid question, but would you use a FPSS with a standalone fuel system?

I wouldn't use one. I had 6 on my car throughout the years. All of them have failed.
