Old Fuel in Tank and Fuel Lines (1 Viewer)

[airwolf8873]

I have searched/read threads on how to purge old fuel from the fuel lines and drain the tank. I pulled the main filler hose on an incline and think I've got it all drained. I put Seafoam in to try to neutralize anything that might be left. When the right panel is pulled from my rear hatch area, there are many lines that appear to run to/from the tank. There also is what appears to be a return line that runs next to the fuel line that goes to the fuel pump. My question is, what are the lines that are behind the panel and do I need to try to flush the return line too? I've got a Trollhole carb I need to install and want everything old out first. Thanks in advance......

I believe your trollhole has no return line...correct? if so, your return line is not needed. The lines in your rear corner are venting only and dont have fuel running through them.
HTH..

There is a return line from the fuel pump back to the tank, I assume this is for "excess" fuel not needed by the carb.

Sorry though, don't have info on how to clean the tank and lines.
