Harley Davidson Gas Tanks Line Leaks

By Dennis Santopietro

Q: I removed gas line on left rear side of the Harley-Davidson gas tanks, 2007 Softail to remove tank and disassemble electrical wires to run them inside Fatboy handlebars. That part is done! Upon reinstallation, the gas line leaks profusely. I went to HD Forum and found o ring part number for female end and bought 3 at Advanced Auto. I can’t seem to get it on the right place.
Any suggestions?

A:Javier, from our experience, it takes a little time and patience to get that o ring to seat correctly. It is not easy. We usually go through a small variety of small screw drivers and picks before, finally, finding success. The best way to avoid this problem in the future is to lightly coat the o ring with grease before trying to insert the fuel line fitting. We know this is of no help to you now. But, maybe you can feel better knowing that we feel your pain! Good luck!

    2003 UC quick connect leaking. Is there a o-ring on the male part or inside female connection? The male part looks to have a o-ring groove.

    Try Fuel Tool 400 o-ring remover and installing tool. Also Fuel Tool sells both quick disconnect seals with stem and spring (MC300) for complete rebuild of quick disconnect.
