SU AUA66 fuel pump diaphragm stem length

Hi,
I have purchased an E10 ethanol resistant diaphragm for my fuel pump, however they have got back to me and said they have one that will fit but they are asking for the diaphragm stem length, as they have two lengths in stock:
2 3/8" or 3".
Does anyone know what the length of the stem is in our SU AUA66 fuel pumps?
Many thanks in advance for any help.
Best wishes,
Mike.

Do not know if this will help or not.

Burlen list two diaphragms

Post 1985...…………………..AUB 6082.

Pre 1985...…………………...AUB 6098.

Otherwise it looks as if you will have to strip the pump to determine the length which will happen anyway to replace the diaphragm.

Regards and stay safe.
