Uncontrolable fuel pressure at idle

[Petro99]

2 weeks ago i took my BEGI fmu apart because i had a constant 80 psi fuel pressure at idle and couldn not adjust it. I found the metal shim had a tear in it. I sent it out to begi for a rebuild because i wanted to make sure the fmu was still good seeing as its 8 years old. While it was away i changed all the vacuum lines with fuel line so it would be a little stronger and i found the hoses looking like they could use a changing. I used 1/4" for the BOV and 3/16" for everything else including that tiny one off the egr valve. I installed my fmu today and while doing so changed the fuel line from the fuel rail to the fmu from 1/4" to 5/16" and the guage from 5/16" to 1/4". I finished everything up and started the car. Now i have no adjustment and im at 20 psi and cant raise it at idle. I dont want to turn the screw in anymore because ill tear the shim inside if i go all the way in. Did i do something wrong changing the vacuum lines or fuel lines? Did BEGI rebuild it and not check to make sure it was in working order? I think the fmu is bad and i got a rebuild for nothing. Im at a loss. Any ideas?

Never mind guys. A new day with a clear mind I was able to figure out the problem.

Just out of curiosity, what did the problem end up being?
