Hi,
Relating the the article in the club magazine on fuel light flashing at low levels and a cure using a relay (issue 449 May 2020 page 42) does not seem that it could possibly work.
I bought the exact same relay, but noted in the feedback for the relay that other people kept saying it does not work as described.) Not put off I bought it, spent a while wiring it up then tested it.
It soon became evident what the other people were talking about. The relay flips from one state to another and not just starts in one state and changes after a delay.
ie.
From the photos I have and the photos in the article I have the exact same board... there are no other markings below is my board

The only thing you are asked to do is remove S5, which I did but removed or not it makes no difference. Joining the two un-jumpered pins disables the relay. You can see on the reverse side of the board how the relay is wired and why it cannot work.
Even Henri's description is the same as mine, which is on grounding the GO terminal the green light comes on, and then after a delay goes off, which is the relay flipping from one state to another.
If I have got the wrong board.. beware as you cannot easily tell... and how can you tell you have got the right board?
Has anybody else performed this mod and if it works could you photo your board. I think it must be that there is an alternative board, that works differently but how you can tell this I am not sure
Hopefully Henri can comment if he is online..I will send him a pm if possible.

ie.
- If its OFF to start with, when state change it will go ON then after a delay OFF again
OR - If its ON when state change it will go OFF then after a delay it will go ON again.
- If the fuel light is off (what we want normally) then when the tank sensor blips the fuel light will flash (relay blips), then go off - which is what happens anyway and when really low it will be off all the time wrong
- The fuel light will be on all the time when full (wrong) then when a blip occurs the light will go out OK, and when really low the light will come ON all the time OK.
