Default high fuel pressure problem, blew a hole in fuel line

fuel system
ur 1000cc injectors
ur custom fuel rail
dual walbro system
no name fpr non adjustable with just a gauge on it

well i was driving home from work yesterday and i was getting onto the highway and got on it and not even 10 secs later i felt a loss of power and raw fuel i pulled over and found out the line leaving my aftermarket fuel pressure reg was torn...i was like holy **** i couldn't believe i call my g/f and she went out and got some high pressure line and i put that in started the car and the gauge on the fpr was reading about 84psi...way higher than i know i know you guys are going to kill me, the only part i went cheap on with the whole build was this no name fpr...and what do you know..i think thats is what is wrong

so anyways i put on another line and just primed it and then turned on the car and after about 10 secs the line started to bubble right before the T heading back in to the fuel lines, it bubbled so quickly that i went and turned off the car and before i could the line split again in the same spot that the first line did....then i was left without the car being able to run...and it turned out to be a very very long night...thats for another time

possible problems i can't think of why all the sudden the fuel pressure would jump so high and then to blow holes in two fuel lines leaving the fpr....i am thinking when i was at wot the fpr failed...i guess they are pretty sensitive..
any other suggestions

i still have my stock fpr....i guess i could throw that on, i don't know if that is made to handle 1000cc injectors with dual walbros system though..

i am kinda at a loss for why the pressure is really high...i checked the fuel system pretty good and all other lines look to be in good shape
