Hi.
The replacement non-SAI pump arrived; removing the locking ring to pull the failed one was painful. Patiently hitting counterclockwise its top nibs with all the care to not damage anything, finally came out.
But this metal locking ring came out rust-attached to an whitish hard plastic ring where it is tightly threaded-on and would certainly break if forced out.
Cannot find the part number to order such plastic ring which is NOT the rubber seal nor identified it on any parts diagram
Seen by time stamp 12:10 to ~13:00 at

So I have the locking ring with a plastic ring inside it and cannot separate, already chipped bits trying

Help please !


The outside of this whitish plastic ring is threaded to the inside of the outer metal locking ring.
The inside of the shown whitish plastic ring is supposed to lodge the rubber seal or the tank lip ?

 

Found an image with the part; but is not an image for any Disco II:



"5" is the plastic ring pictured in above post inside the metal lock ring; "4" is the rubber seal; "3" is the metal locking ring.

 

I also need new ring components in order to replace my fuel pump... subscribing.
