So I'm about to replace my injectors, put in a new (and adjustable) fuel pressure regulator, and a 255lph pump.

How do I de-presurize the system before I start taking things apart?

if you wait a few hours after driving the car the pressure drops as the fuel makes its way back to the tank. you can always press on the schrader valve to release the pressure.

where is that valve located?

its the one that when you look at it you think "hmm **** may come out of that if i press that nubbin in"

on the fox body it is at the very front of the motor on the passenger side. you will see two metal lines coming off from the fuel rails. one of them will have the schrader valve sticking off of it. its the supply line that has it.

yea, be careful, i'd let the car sit overnight before venting the schrader valve, GL

Just let it sit few hours, you wont need to vent it the pressure will be gone.
