what fuel line repair kits will fix connections(3) to fuel filter ?

There are o-rings and fittings in the box with a new fuel filter. Put a new one one on and that should do it. You probly needed a filter anyway.

I HAVE A NYLON FUEL LINE REPAIR KIT WITH NEW ENDS TO DO THE REPAIR PROPERLY AND THE SAFEST. YOU CAN GET SOME VARIOUS PIECES AT LOCAL PARTS STORES THAT REQUIRE BE HEATING AND PRESSING ON. THEY COME WITH ENDS ATTACHED. I HAVE NOT KNOWN OF THESE WORKING GREAT BUT IT IS A DO IT YOURSELF OPTION AND THE ENDS WILL WORK WELL WITH THE FUEL FILTER. I HOPE THIS HELPS THANKS
