Live dangerously and take a chance on this. Or you could just drop in a new assembly Some people I know will reverse the leads to a fuel pump to try to free things up, I'm just not sure that this would help you with a regulator. 10 PSI of air backwards through the regulator???

We took the pump apart and put an air nozzle to all the ports but it didn't do anything. My friend ordered a new regulator so hopefully that will fix it.
