General uno uno uno...questions

[JRB21]

Hi, I hope somebody can help me. I have a few questions regarding a '95 uno fire.

What connections is their on the fuel inlet pipe?

Mine has a small black rubber fitting (looks like a fuel filter but is not see-through), that has two wires attached to it. After this is the fuel filter and then the fuel pump.

Can anyone tell me what is this black rubber thing?

How can I test if my fuel pump is not working correctly?

When decelerating my uno makes a whining sound, I have drained and replaced gearbox oil, but the whine is still there. Any ideas?

Your fuel pump will have a live and an earth on it so just attach it to an old car battery or jump leads and it should spin. Any chance of some photos of what u want us to tell u what this rubber thing is?
