Good/Bad Experiences when changing to 3/8" fuel line & sending unit?

The 3/8" steel line I bought needed some massaging and didn't fit super great. I replaced mine because someone had hacked in an electric fule pump and it was rusty. My pickup was a Sprecta as well and I experienced what cpearce did. Just reuse your stock lock ring and be sure it has been turned to enough to seal. I didn't do that and had a leak. Good luck finding much USA made and frankly, some US made items are not the quality of 20-30 years ago. Some Spectra is made in Canada. I find more issues in the poor design of replacement parts than the actual build or material quality.
