Good evening everybody, I am a new member here so I will introduce myself in the "introduce yourself" forum if it has one

I am new to fords due to owning numerous rover diesels, and decided it was time to upgrade the motor. Bought a mondeo 130 TDCI zetec with 125000 on the clock, and in excellent condition (loads of cool gadgets that I have never had on other cars!)
Here's the problem, after driving the car there is a small diesel leak coming from underneath the car, nothing major, but after a few hours there are a few drips of fuel on the floor. I have tried to locate it whilst the car was on jack stands but could not. I cleaned it up and had the engine running and there was nothing. It only seems to do when the engine is under load I.e while driving. I am hoping that it is a loose something or other and not leaking from the pump. There does not seem to be many answers on the net as I have googled it (that's his I found the forum) so I hope somebody can help me
Many thanks for taking the time to read this
James
