Mechanical fuel gauge

My "osculati" or whatever generic orange plastic 70 fuel tanks have the usual fuel sender attached to them. They are WHOLELY inaccurate.. I'm about to go nmea and add a fuel flow meter and thought I'd completely lose the 2 gauges off the console as the One thing they don't do is tell me how much fuel is left!

But what I'm looking for is just a mechanical fuel gauge to replace the 2 senders so I can look at them before launching.

Does anyone know where to get these from.. There are some from the USA but I was hoping to find them a little closer to home. It looks like you can get some that replace the fuel filler cap

Anyone got any experience of these.?

In my experience mechanical gauges aren't any more reliable. The float can stick tricking you to believe the tank is fuller than it is. A dipstick is more reliable.

Hmm interesting replies. The tank level gauge, I guess replaces the fuel filler cap?

In the last 12 months I've been finding twigs and using those as a dipstick (.....occasionally I've dropped 'em in e tank as well which isn't clever). I guess the best of both worlds would be to add a dipstick to the filler cap- you've got to take it off to check and the stick shows you a wet level.

All gauges are just an approximate the best tank I had was with a clear window gauge down the side but even that's no good if you carnt get at it to see it, dipping ok if you know your boat is level you can easily be in a big tank better off than you think depending where the filler is of course with the stern down. A spirit level will soon tell you that next your on the water how your tank lays. P for plenty best gauge I find.

Well, a twig has it's place, but possibly not in your tank.

Don't dismiss the concept. The RNLI and others (me) are huge fans of the dipstick. I use a carbon fibre rod to dip my tank. If you have good access to the tank, a dipstick is infallible and a major confidence booster. If you calibrate the dipstick with known additions of fuel, you're sorted for life.

If you calibrate the stick - do it when afloat - not on the forecourt.
