When I started to re-connect the fuel line to the drivers side fuel rail on my 2001 4.0 the connection was sloppy. Apparently there should be an 'o' ring. Can anybody give me a part number or specs. Ford dealer has no idea. Thanks

 

Welcome to the forum

I don't see it at my parts look up place either.

You may need to just measure size and get some O-rings, plumbing o-rings will work in a pinch, you can get a bag of them in different size for $5, but fuel resistant would be best
