I found that what I believe to be the in tank filter at the end of the fuel pickups has fallen apart in the tank and the bottom of the tank is covered in black flakes which got sucked into the carb....(or purchased some bad gas)

its a 91 SC so I figure while its all apart I should replace the 17 year old gas lines and add some in line fuel filters to the system as well as add a primer kit.

Does it matter what type of hose I purchase? what is best?

clear urethane, black rubber.... does it matter?

where is the best place to find the plastic clamps? are zip ties ok?

I do like the fact that the factory gas line has reserve and the main line printed on it.... might the factory line be ok still? seems pretty old.
