Bastad fuel sender has packed up.
It only ever gets to 1/4, and soon sinks right to the bottom of the gauge after a bit.
Is the little float ball hollow? Could it have a leak, so that it fills up and sinks after a while?
Do they bolt in, or do they only have the lock ring on top?
If i'm going to replace the sender, is there any thing else i should look at while its in bits?
