2.0 XDi Diesel Leak!

hello all!

went for a drive earlier and noticed a strong smell of diesel, when i pulled over i realised a big puddle of diesel coming from under the middle of the engine bay dripping pretty intense!

only a week ago i changed all the hoses on top of the engine because they were all split and causing issues. but from inspecting it today the hoses all look intact with no trace of leaking?

does anyone have any info towards where a possible leak could come from and whether a big expensive job is around the corner!

thanks before hand for reading and touch wood ill have her back on the road diesel tight sooner rather than later!

Injector washers?
Maybe leak from fuel hose connections to the pump, or on fuel cooler connection to pump.
Also you have a solid fuel hose on side of the engine (you need to remove airbox to see them)

thanks for response i will try those now!
