Do not trust the gauges. Get a dipstick made or buy one that someone else has already done the calibration for.
You don't say whether it's a group or club aircraft. If it's club and it flies just before you then I'd suggest doing your weight and balance beforehand and then loitering around for when it gets back - making sure only the fuel you want is put in. Either that or get accurate weights for you plus pax - you might find tabs fuel is ok.
