Fuel leak

[scott82070]

I have a 97 PSD just changed fuel filter and now have a small leak. Leak only occurs when I turn the engine off. Any ideas?

Where is it coming from?

[bigcountrysg]

usually leaks occur while everything is under pressure. As in when the truck is running not when the truck is shut off.

could be an injector pump depending on where it is coming from.

I don't know if the older ones are the same or not, but I had a leak that only showed up when the truck sat for a few hours (2000 F-350). Mine was the o-rings on the filter bowl drain.

I had the same problem but it was the mechanical feed pump behind the fuel bowl.

Take a good look down into the valley of the motor and see if you can tell where it comes from, could be filter o-rings, the filter lid seal, fuel pump or you might not have got the water drain valve closed all the way.

Thanks for the response - I haven't had time to look to see where it is leaking from but I will take a look this weekend.
