Fuel tank sender unit suggestions

Merry Christmas to you all....I always turn to you guys 'cos someone always knows the answer!
Ive removed the rotten floor of my boat and have removed the fuel tank. The fuel sender unit is not working. In fact its the wrong one for the American Honda fuel gauge I have (long storey!) I think its a standard fitting with five bolts holding it down. the resistance is 240-33 ohm . The tank is 200nn deep. Have you any suggestions where to start looking for one? Im open to a good reliable make,as accurate as possible,float design,orientation of the float etc etc Hints tips? Nik

You need a WEMA American spec sender https://wema.co.uk/collections/marin...nt=29703069767
I have an old 7" one which I can let you have if you don't want to buy a new one. It works fine and suits a 200mm/8" deep tank as you are supposed to have 1/2-1"(steel v plastic tank) clear from the bottom. I've also got a new 200mm one if your tank is just over 200mm

I've used ASAP supplies and shop4tanks.co.uk for sender and gauge. Both were very helpful.
Gauges aren't expensive so don't feel forced to stay with original gauge.

Thanks for the kind offer. Can I get my measuring tape out and get back to you about that. Which are better sender units ? The one with the vertical moving magnet or the swinging float one?? Is one make better than another? Nik PS Happy Christmas to all.

The vertical dip tube type are better but no gauge is totally accurate due to the nature of a rib and associated fuel movement. They are a guide only and the only accurate way is with a fuel flow meter to determine how much you have used from a full tank or your last fill volume. Many modern outboards have this function 😊

RIBase
Tek Tanks do a few different types of sender in their catalogue.

Have you though of fitting a digital gauge?- this works off the fuel used via the engine management system.

I've found mine to be highly accurate - far beter than an analogue sender in a long narrow tanker which is pretty inaccurate.

Thanks for the replies and suggestions. I have a pre digital honda 90 which is great for the job. The tank is 200mm deep 119 litres. Very flat! Ive been on to WEMA uk who do a 175mm high resolution one in 316. The 200 mm one would be too long ..just. For those of you who don't know it is a vertical stainless tube with a floating magnet around the outside. Inside is a series of reed switches every 10mm. Very simple. Ta Nik
