I replaced fuel pressure regulator. The quick connect hose would not come off, so I soaked it in hot water. It came off, but the fuel-resistant lining has detached - still stuck to the old regulator. So the hose is loose on the new regulator. I put a hose clamp on it, but I can still smell petrol sometimes. I presume those hoses (the return line that clips onto the pipe on the firewall) is no longer available. Is the quick connect fitting something standard that you might get from a performance shop or marine engine fitters?
