fuel line help please

I was under the hood checking the oil and noticed a fuel line (I believe) on the driver side of the motor. In the picture, I've pointed arrows at the line. My question concerns the black plastic which connects the rubber hose to the metal tube. I noticed that it was loose and the plastic piece was out. When I pushed on the hose, fuel sprayed out,:eek:oohhh: so I pushed the plastic into the metal housing. It doesn't seem too snug (pictured with connector all the way in). Is this as far as it goes? I must have knocked it loose when I was changing the plugs. I think I'll have to wrap a wire or paper clip around it to make sure it doesn't come loose while driving. What are your thoughts?

I wouldn't drive it ... it is a fire hazard if fuel sprays out so easily ... replace ... replace ... replace ... cheaper than a new car ... exhaust mainfolds below ... HOT.

Odd connector. I ran into the same thing when I did my fuel filter. Felt loose but was sealed well. I could not figure it out so I cut the line and used an old fashioned hose clamp. I know that many will frown on this but if you have enough 'slack' in the line you could cut it and use a hose clamp to attach it to the metal line (beware of the fuel line pressure).

Or you could always go buy the line from the dealer and have them replace the whole thing...

Avusblue,

Watch it! Very dangerous area.

The plastic clip will _RELEASE_ the connector when pushed into the sleeve.
It is supposed to be free and rotatable when the connector is correctly mated. If it does not move freely, the connector is not secured.

If so forcefully push the connectors together to get a clicking sound and a freely moving plastic clip.

Further, never under any circumstance put a hose-clamp on a high pressure fuel line. It is 5 BAR pressure in an M5.

I´d definitely get the hose replaced. Screw-locked hose clamps are no to be trusted with high pressure fuel.
