Fuel gauge won’t go above 3/4
 

Probably a dumb question and yes I’ve searched but can’t seem to find any how too’s on this. My gauge won’t go above 3/4 even though cars full. How do I get to the level sender(s) and any videos on how to access.
Cars a STI hawkeye if any use.
Cheers

Look up changing a fuel pump, should be of use.
