So im hooking up and blocking off some of the ports on the intake and I go to snap back on the fuel line back on the fuel rail. And instead of them snapping back on like they should it just slid in but didnt lock in place like they they should. I mean I could take them off and back on at will. Didnt even needd a fuel disconnect tool. So is there some kind of snap ring inside of that fitting that connects to the fuel line fitting?.

 

Did you try both? If you put the large one on the small fitting, it'll do like you describe. I don't think you can just replace the fittings, but you might be able to bend the tabs a bit...not really recommended though, you don't want them coming off. What did you use to get them off originally? I've had mine off many times and never had them fail...

 

Agreed, Ive head mine off many time as well, but the car has been in rebuild mode for the better part of 5-6 months and I havent had them connected since then. I'll try them again tonight and see what happends. Maybee I was just tires, we'll see.

 

They should have a spring in them that may have rusted.WD to the rescue.
