Smelling fuel

[Ted K]

When I start my 535is in the mornings when the engine is cold I can smell fuel. Once the engine is heated up I cannot smell it anymore. Can anyone tell me what the problem might be and how i can fix it?

check the hoses where they attach to the fuel rail!

the engine, just above the inlet manifold. I've replaced mine at least 3 times.

is that near the intake manifold

hose is deposited over the intake manifold. Just ahead the firewall, between the inlet tubes to 5 and 6.

Also check the hoses coming up at the driver's side of the engine, just under the center of the intake manifold (Incoming and return fuel hoses). And the hose attached at the fuel regulator at the front of the engine. I have not had problems with those, but who knows?

I've had a few injectors leak externally where the plastic meets the metal body.

They will look wet and grimey.

Never personally saw this.

until after they have changed every hose and clamp, and still smell gas.

The old BMWs are worse with the few inches of hose between the rail and the infector. Used to call that set up -Der Flammen Werfer-
