2013 Jaguar XF 3.0 AWD supercharged- The high pressure fuel line coupler on the LH side of the engine by the firewall is leaking. It is the front male part that is seeping. The female o-rings are fine. Is there a repair for this? Does anyone know the name of this part and/or have an O.E. part number? Thanks, Phil

 

Good car info so thanks for that. But can you post a picture of what your problem is?
These DI engines have very high fuel pressure and the SS fuel lines come up on the RH side of the engine to the fuel pumps then onto the engine. These seal with metal to metal seals and no O-rings?
Nothing attached on the firewall?
Do you mean the plastic tubing on the LH side of the engine?

I think you mean the low pressure fuel coupling....
