My 4/4 is the same - there are many Morgans of a certain age which are similar.

I generally fuel up using the tripometer as a guide ~ 250 miles or so, rather than the fuel gauge. To be honest not many of the gauges are to be relied upon. Well, it is a Morgan after all.....

It could have happened when i topped up the tank but with a extended range tank l usually stop before any "click". No need to give the tank a good shake the roads in my area do a very good job at this. It looks as if l do need to remove the float from the tank l would need to remove the tank first as there is very little head room to the ash frame.

My +8 has always done that, the 4/4 sticks on full till nearly half tank is used and the M3W tells you whatever it is feeling at the time none of it accurate.

Of course you could go that difficult route first but I would try the connection route and see.

Obviously I will be testing all the connections first, l was mearly voicing my frustration that if the float was the problem l would need to remove the tank in order to extract it.

No problems with the electricial connections so l guess it must be a float/sender problem. Looks like a big job to remove the tank especially in my tight garage so I'll top the tank up then rely on the trip counter to warn me when its getting low

Most owners rely on the trip miles, even when they have a working gauge as it's less risky
