Humber diesel leak

I have noticed that a litre or two of red diesel is starting to collect in the bilge on my Humber ocean pro. It has an underdeck fuel tank. Any suggestions as to the likely source or how to trace the problem without removing the deck which would be a major undertaking. Thanks in anticipation.

are there any access points from the console or on the deck that you can check hose and pipe connections for leaks etc?

There are two 6 inch square plates on the deck which I will remove when I can. I tried yesterday but the screws were impossible to budge.

you may need to remove them carefully using easy outs, not sure if they are just self tappers into the hull or machine screws into a captive nut of some sort but getting those inspection hatchs off is key to understanding if you have a minor or a very major issue

cheers

Before you do anything check the engine bay and make sure there are no leaking pipes or filters etc - it could save a lot of work!!!

The engine bay looks OK.

I have just had a similar issue (but with petrol ) resolved. In my case there was a leak in the fuel filler line, at the junction with the tank. One suggestion offered during the "fuel in the bilge crisis" was to check the seal where the fuel sender was fitted to the tank, apparently it can slip. Worth a peek?
