Help Id'ing Connector

[Alexp]

Can anyone help me identify the connector that sits behind the diesel primer and what its purpose is.

 

I've been having trouble with my 1.4 HDI not starting if left standing for a while and found this connector unconnected.

 

Thanks in advance.

Welcome to the forum.

 

A bit more info might help

 

- What car is it, what year and how many miles

- is the servicing up to date

 

A photo of the part would help and is it an electrical connector or pipe.
