Fuel Command Center 2 discontinued?

Hi, I've got a FCC2 running my Go EFI 600 on my truck.  This weekend while climbing a hill going down the highway, the truck died.  I figured it was just vapor locked, so I let it cool down and it fired up.  Well, it died 3 more times in 100 miles and I ended up getting towed home, but it will idle all day long.  I checked my FCC2's pressure gauge, and it's at 40 psi.  Is that enough pressure?  I thought it was supposed to be closer to 60 psi.  I've e-mailed Fitech, but checking their website I no longer see the FCC2 listed under their products.  I wonder if they're having issues like they did with the first gen FCC?  Anybody heard anything?

Yes, your system should be at 58psi.  Do you have it wired directly to the Orange wire? If so, increase your PWM to possibly remedy....

As for the FCC2, I think it is a much better design than the original.  Very few issues have been reported.  The manufacturer of the FCC2 along with the entire fuel system line is a separate company.  Last I was informed, Fitech is in contract negotiations at this time.

If you do have a pump issue, you could always remove the pump and replace with an equal replacement of another brand.  I recommend Aeromotive.

Check the line that connects the pump to the discharge port.  Common that line breaks or leaks.  Replace with EFI rubber hose and EFI hose clamps.

Thanks for the quick response, Austin.  Yes, I have it wired directly to the orange wire.  Excuse my ignorance, but what is PWM?  Haven't spotted any leaks or anything, been going through everything with a fine tooth comb looking for issues I might have missed.  System has only been on for a couple months and a couple thousand miles.  Truck has been working flawlessly until the "vapor lock" incident happened, and now I'm grabbing at straws.  I will attempt to raise the PWM like you suggested once you let me know what that is haha.....otherwise I don't know what my next step is.

Oh, and I found that Hyperfuel has their own site now with the FCC2 still listed.

Yep, they still have product.  Not available through Fitech.

The hose issue will be inside the system.  Must open it up.

If you are vapor locking, you need to look into how to keep the FCC2 cool.  This is why I only recommend in tank pumps.

Handheld Definitions in the Members section will help you understand PWM.

Just checked the section and read the PDF, very nice and handy.  So, just to be clear, I should still set it at 40 for my FCC2?  40 is actually increasing the duty cycle from the 74.5 or wherever its set now?

No actually the other way around.  Lower number slows the pump.  If you have been running the pump with the default PWM, the pump may have overheated and is beginning to fail.

I had pressure problems with my FCC2 when I took it out the box. It didn't give me any pressure. I opened the sump and found out the pump itself was broken in half. I bought a replacement pump for FCC1 from Jegs and it's keeping steady 58psi.
