On my 08 RKC, I've had mine apart several times and haven't needed a new O ring yet. Checked for dirt that might be keeping things from sealing?

 

i tried to match the thread, was told it's metric not a pipe thread.. iv been looking around

 

Can you get the thread pitch and OD of the outside of the threads. Didnt know it was metric but the book has metric, SAE, and british imperial.

 

Here is a good place to get the metric to pipe adapters.

What is the year and model is your sled? Here is a good site for break downs, part #'s, and prices:http://partsfinder.onlinemicrofiche....dmc&A=544&B=42

 

iv got an 01 roadking classic. just need to replace the part that threads into the tank with the barb on the inside/90* outside so i can connect the fuel line a different way.. more relaible

im having a hard time finding the exact same threda pitch too. lol

 

Go to a auto parts store or sears and pick up a SAE/metric pitch gauge.
