two choices, either change the o-rings inside the fittings (14mmx2mm) or change the fittings on the tank. Some will say the oil drain plug o-ring will work for this, but it didnt with my 2000 ultra. I had to go with a metric sized o-ring in the fitting to stop a slow drip. They MAY have changed the fittings slightly between the Delphi injection (2002+) and the Magneti Marelli (2001 and earlier)

Lots of threads on changing the quick conect o ring. I thought it was a PIA. I had my mechanic put a new quick connect on, and replace the in tank fuel line, which is prone to pinhole leaks. 2003 FLHTCUI100.
