What is a fuel shutoff valve and what does it do?

The fuel pressure safety switch cuts both the N20 and fuel solenoids when the fuel pressure drops.

Once the system is installed you should not have to be removing it.

If you have to remove it for any reason like I did to install a fuel pressure gauge then what I do is turn on the truck and open the hood. Then I pull the fuel pump relay out and wait until it turns off. After that it has very little fuel left in the line so I just put a rag under the line and remove.

With the valve you will also get a little fuel left in the line even when closed.

I realize this, the system has been installed for 3 years.

I realize this, the system has been installed for 3 years. I plan on removing it temporarily to create a new bracket and i dont want to be "down" the entire time as i dont know when it will be done. I'd rather have a valve instead of a cap on the fuel rail.

sounds like a waste of money to be honest. pull the line from the fuel rail and put the schrader valve back in. when you're done with the bracket just put it back together in reverse order.

Like suggested above just run down to your local parts store and get a sharder valve for a few dollars.
