Bradford white pilot tube

Is there anyone out there who has had to replace the pilot line on a newer bradford white water heater? Bradford white won't sell the pilot line seperate, you have to buy the whole pilot assembly. It is and 1/8" od pilot tube with an 1/8" breakaway fitting on one side, and a 1/4 x 1/8 on the other. I would like to be able to sell my customers just a pilot line instead of stocking a 100 different pilot assemblies. If anyone has any ideas, let me know.

Thanks,
Matt Bryan

If BW doesn't sell it seperately except for the assembly, for liability reasons, and since you are dealing with gas, installing the assembly would be safer.
