Satria fuel sending unit

[rickardo]

Hi guys
I have an issue with my fuel sending unit in my 2001 Satria GTi
My fuel gauge isn't working correctly and I suspect the sending unit.
Reason being that when I replaced the fuel pump I noticed some rust forming inside the tank which I have had cleaned out.
This vehicle sat for a year without use with hardly any fuel in it.
My guess is that the sender unit is contaminated and needs some cleaning etc.
Does anyone know what ohms reading I should be getting from empty to full ?
Thanks.

Short the sender wire to earth and the gauge should read full. Open circuit should be empty.
Resistance should vary from short to infinite as you move arm.
