After I replaced my fuel filter I had my wife start the car while I was under it to check for leaks. The fuel filter did not leak but the line leading to the fuel pump did. While the car was running I foolishly attempted to tighten the connections to the fuel pump and got a good spark. The car stopped running and I have not been able to get it started since. I realize I'm lucky no fires started so I'll live to make many more blunders in the future. Did I destroy the fuel pumps or worse? Thanks for any help.
