That probably means the pump itself is fine. I think the sensor is on the fuel sending unit set, not the pump assembly. The fuel unit set is the float and guage sensor. I'm not 100 % positive as I haven't had to change it out yet on mine, but check it out. There is a big price difference between the whole pump assembly and the fuel set or just a sensor.:shrug:
The dealer says it is on the fuel pump assembly unit, he showed me the whole unit that is needed, I have found an 07 one on ebay Uk, which is reasonable priced, so will try that and let you know how it goes.
There are actually 2 different floats that are involved with telling the fuel level. If you do a search on here there is a thread where a guy went into great detail about it. He even tells how to check them I think with a ohm meter. It could be either one of them that are bad. You might want to check it out and look at that thread close you might be able to fix the one you have. I will see if I can find it and post a link.
