I'm sure you'll get expert replies. My reply is simply to thank you for reminding me of the word "tundish", which I don't think I have heard since my (Derbyshire) parents used it. I assume you mean a funnel?

Often condensation is the issue. And the best way to reduce that is keep your tank filled as full as poss. and top up regularly.

 

Once you have done it once and got over the initial cost of a full tank it's just as cheap then to regularly top up.

Check that the O ring seal in the filler cap is in good condition, especially if the filler is flush with the deck. Raised fillers are less likely to let in rainwater (or spray from leaking gates).

Make sure you have a good seal in the filler cap .

Make sure that splashing water (rain, lock piddlers etc.) cannot enter via the vent.

 Check the diesel you put in has no obvious water. Draw a sample onto a clear glass tube or jam jar.  It will be slightly cloudy if there is gross water contamination.  Or check it with a Shell water detector kit.

Dip the tank with water detecting paste about once every three months.

And pump/drain the bottom of the tank every spring until you draw off clear clean diesel.

1) Take your boat to a marina, or use a passing fuel boat to avoid the condensation building up in the empty Jerry-cans.

2) Use a separate filter that removes water out of the fuel before it gets to the engine

 

A couple of examples -

Add Fuelset every time you fill up would be my advice.  It won't stop the water getting in but it will deal with any that does.

One of these days I will get a big glass jar, put a litre or so of diesel in it, seal it apart from a little breather hole, stick it by the fuel tank or somewhere damp and horrible and see if it gathers condensation. Apart from possibly a little misting from the initial air that is in there I bet it doesn't.

If you go the route @Alan de Enfield suggests above, remember to ensure that any with a transparent bowl meet BSS. Only a few clear ones do. Also bear in mind that any drain plug must be metal and not plastic.

To accurately reproduce the envirinment in a tank you will need to use a steel 'jar' and stand it such that the bottom 1/3rd is in the canal. and top 2/3rds in the Sun

Lock piddlers? :...is this a Derbyshire habit?

I put some grease on my brass filler cap, , it might be causing gasket to deteriorate.
