Thank you for the help. It led me down the right path to find out that they're called residual pressure valves. I'm calling Wilwood tomorrow to check application and part number before I order. I'll post the part number here in case it helps anyone else.

SSBC also makes them, but that looks just like the one that failed

As far as the fuel leak, I'm stumped. I've been over that car several times...Looks like it's time to "Call the guy". That's why professional technicians are professionals. Thanks for the help.
