Replacing Fuel Tank, Lines, Tube...Suggestions?

Hi All,

I've been putting off this project for 3 years but now it is time to get it done. My tank and probably my lines also are cruddy and need to be replaced. I was looking to get a spectra tank and a fuel sender with a return. I also have to replace the filler tube because a PO had used epoxy to connect it to the tank, which leaks. I want to do this once and do it right. Any suggestions or tips are greatly appreciated.

Thanks in advance -Billy
