It is available at parts stores. I get mine from Amazon as it is about half the price. I think it was around 25 bucks on Amazon and around 60 bucks locally.
Bosch 4 bar 0280160575 This is the 4 bar unit for regulating 58 psi. There is a 3 bar unit for 43 psi.

I have the new Handheld V2 that FiTech sold me after I first had the on/off controller issue. I did the initial set up with the new controller so I’m guessing that I am starting fresh and the ECU is still learning.
I just started the engine, seemed to idle fine. Let it warm up to temp. Took it for a 10 mile ride. Went well until I got on it a little from a stop. Went up to around 3000 rpms but didn’t want to shift (c4 tranny) let off throttle a little, it shifted, then Afr‘s went to 20 and ran rough again. Nurses it back to garage, let it idle bounced between 600-800rpms on its own. Gauge on fuel line was showing past the 100#. Shut it down
I don't believe swapping the handheld would reset your learns. I would swap out hour pressure regulator and reset learns and start over. I have had this system running on one bronco for a few years now. It never ran bad, but has taken some time to optimize the settings. You might also check and see what version of the software is actually loaded on your ecu and your handheld. If your programming is current in the handheld it might be worth a shot to upload it again to the ecu in case the ecu is not running the latest software. The latest software helped me improve a couple of nagging driveability issues.

I ended up removing the FiTech and installing the Holley Sniper. It only took 2 hours since most of the work was already done. Controller worked. Fired right up! Test drove great. What a difference in power!
I removed my fuel return line from the poly tank connection that I had drilled and tapped and found it was restricted due to the hole too close to the top of the tank. I and bought the EFI Return Line kit from Summit Racing and installed that into the rear tank fuel fill line.
When I first fired it up, I got normal fuel pump pressure (around 60 lbs). After driving, I pulled back into shop, put it in park and it ran a little rough for a few minutes trying to find itself. I opened the hood and the pressure was back to 100 psi.
Later, I took the wife and kids for a ride, picked up pizza to go, ate while we drove some back roads. After about an hour pulled in a drive to turn around and it stalled. Turned the key and engine would not turn over! Had my tools and tester with me. 30 minutes later I found I had not hooked my ground from my manifold back up to the Neg battery post! LOL I should have known when it was turning over slow previously? I looked around for burnt wires from where it was pulling ground, but didn't see anything. For some reason, it also started shifting into R & D really hard! Got it home. Next day pulled the shifter apart and determined the cable is screwed up. Could it have been pulling ground from the shift cable and melted it?? I ordered a new shift cable and new Sidewinder shifter.
I love my Bronco!! Its work, but worth every minute of it.
