It's not from fuel pressure. a friends GTO using a Holley blue pump(14psi max.?) also had this happen. The fuel itself deteriorates the line. Like I mentioned in an earlier post I saw this happen in four different cars with four different fuel systems. They've all converted to aluminum hard lines with a/n fittings. When those braided lines fail you better have a good fire extinguisher handy because even at 9 psi you won't believe the spray shooting from the ruptured lines.
