Sounds like you might want a shop to take a look at it.If it is in fact a pressurized fuel rail that is damaged (other than cosmetic) then it should be replaced NOT repaired! It's GAS --------vapor+spark=FIRE. Guessing not worth your life-please!
HEY DUDE; DONT WORRY ABOUT MINOR SCRATCHES ON THE FUEL RAIL.
WON'T HURT NUTEN!!! WHEN YOU GET THE ENGINE RUNNING CHECK FOR
ANY LEAKS IF YOU HAVE ANY IT WONT TAKE LONG TO SEE THEM JUST
DONT DRIVE UNTIL YOU ARE SURE OF NO FUEL LEAKS.
PS, NO SMOKING!! DO THAT AFTER IT IS FIXED.
