Fuel Retrun line clip missing - Replacement Source?
 

I began noticing a fuel odor near the rear of the '02 V70/XC recently, so got under there this weekend to see if I had a leak. Fuel pressure seemed fine, and car was not having any issues, or throwing any codes. I also did not detect any leaks on the pavement under the vehicle. What I found was what appears to be the Fuel Return Line that has a plastic fitting that looks like it had a clip that secures it to the nipple coming from the tank was disconnected. I pushed it back on, but without the retaining clip, I'm sure it will work it's way loose again. Where should I look for one of these?
