I RECENTLY DID THE FUEL PUMP TRAP DOOR MOD ON MY 87 IROC, I CUT ALL THE FUEL LINES OFF CLEAN WITH A DREMEL BUT FOR SOME UNKNOWN REASON ONE OF THE 5/16" LINES CONSISTENTLY HAS A TINY LEAK, ALL THE LINES WERE PUT BACK TOGETHER USING QUALITY COMPRESSION FITTINGS, AND I EVEN REPLACED THE FITTING ON THIS LINE TWICE, BUT THAT DIDNT SEEM TO HELP. SO I WAS THINKING ABOUT JUST USING SOME RUBBER HOSING WITH DOUBLE CLAMPS ON EACH SIDE... WOULD THIS BE A GOOD IDEA OR ANYONE HAVE ANY OTHER SUGGESTIONS? THANKS FOR YOUR HELP

 

Could always replace the entire line that you cut.

 

rubber hose will work they make fue injection rated rubber hose(used them on wifes 97 grand am when i couldnt get fuel filter off without special too)l.works great no leaks just besure to clampthem nice and tight
