Koso RX1N Which fuel sender?
I have an MK alloy fuel tank and ZX9 engine. Thinking of getting a Koso RX1N set of clocks and see it can use 100 or 510 ohm fuel sender but have no
idea what sender would meet those specs? Anyone point me to a suitable sender?
Cheers

Nice one cheers how was it to setup?
Hoping to fit it behind the steering wheel as it seems pretty small. Did you use the speedo sensor and does it work ok?

Everything so far works. Haven't tried the speedo yet, as I have no prop, but revs, temperatures, warning lights etc all work. It was a doddle
to get working.
Mine is fitted behind the steering wheel. It seems fine with the Sierra wheel (and shroud), not tried a smaller wheel yet.

I got an MNR supplied fuel level sender. Not sure what it is really, but wanted to advise you on setting it up correctly. First of all, check which
way it works (when does the Koso show it's full or empty), then adjust the sender's arm so that the full travel you get in the tank will
register as totally empty to totally full on the Koso.
This is what we did and I am glad we thought about it, otherwise the whole thing would be useless...
Just my ideas...

Cheers for the advice. So basically you modified the sender to show what you needed on the Koso. Did it really show when it was empty or full or just
near enough? In other words can you move the sender to the empty or full position and tell the Koso?

In the end it really showed when empty and full. What we have done is we connected the Koso to the battery and the sender unit taken completely out of
the tank. What you need is the sender arm travelling the full distance from top of the tank to the bottom of it and at the same time using the full
travel of the potentiometer as well. With our shallow tanks this is tricky, we needed to shorten and bend the arm. We held the unit next to the tank
to see the min and max positions of the arm, we changed and tried many times until when the arm was on the bottom of the tank the Koso showed emty and
when we moved the arm completely up, it showed full. Note: when you move the arm, the Koso will delay showing the changes on the unit to ensure that
the levels do not jump up and down when fuel is sloshing around in the tank...
I hope this helps...
