I was driving back just then and parked. I smelled the fuel when I exited the car so I poped the bonnet and found the Top of the injector is wet with fuel and the fuel rail is a bit damp with fuel as well. I guessed the fuel are leaking in a form of spray then.:2eek

Did some research and found out the pulsation damper tends to fail after some years. But would PD failure cause leaking at the top of injectors? Otherwise is it just my injectors seals getting old?
Anyone had some similar situation?
I had a look on New PD and they are 28x USD, quite expensive for something that simple really.

Change all the injector seals for what they cost, they go hard and brittle after 20+ years of service. I found all mine had gone that way. Also make sure your rail is actually held down securely, its only two nuts and could come loose.  They PD has known to fail but generally not a cause of a fuel leak but all the items including the regulator have copper washers as seals so may be best to check they are all tight and leak free.

When the injectors seals go it only takes a very very small bit of it to spray an enormous amount of fuel, they really are high pressure.  I would never want to see your car go up in flames.

If it is the PD then you can get rid of it.
