does anyone know how to clean the inside of the fuel sending unit tube. it is varnished up so bad that the float doesn't want to slide any help would be greatly appreciated. thanks in advance

theres a nut on the bottom about 5 mm af , take it off and the cover will slip off so you can see inside , there are a few posts on repairs to the senders have a search for them , it covers cleaning in one or two of them

i did more searching and still came up with nothing. The problem i am having is i removed the tube from the sending unit and inside the tube is full of chunky grossness for lack of a better word. i was just curious if anyone new of a cleaning product or a trick to get all of the varnish and chunkies out of the tube itself.

Try combustion chamber cleaner or carb cleaner. Both can be found at most auto parts stores.
