Is " sock filter ' on end of fuel pickup tube in gas tank replaceable,
without having to buy new sender unit ?
The old one is on tube tight - I'm reluctant to get too forceful in
trying to remove it unless I know for sure it comes off tube -
since I will put original sending unit back in if necessary.
The existing sock filter has slight degradation where it touched
bottom of tank.
