Fuel Rail O-ring

Alan McDermott said:

Does anyone know where the blue O-ring seats on the Fuel rail to lower intake?

The lower intake has a metal tube with a flange on top, where the fuel rail sits. Does the O-ring go on the tube below the flange, on top of the flange, or up in the fuel rail where it seats?

I would post a picture but I don't have a hosted site to put them on.

Thanks,

Alan

Every fuel injection system I've ever worked on, the oring goes on the injector like the picture below. Looks like on yours, the oring peeled off. Make sure it's not damaged.

And don’t reinstall them dry! They need lube

I applied anti-seize to the o-ring.

Now I need to put a new fuel supply line from the connector in the rear of the engine to the fuel rail. I have the new one, just don't know how to remove the old one. it looks like a metal compression fitting with "teeth" that hold the fuel line secure.

Any ideas?
