Went and patched the fuel lines with fuel injection host and it sealed but then sprung a leak further down.
Such is life. I have added steel fuel line to my E-Bay watch list. Fortunately I now have my own tubing flare kit so I can take advantage of the fact that this stuff comes in rolls and I can just either re-use the existing nuts or buy new replacement ones. That means I pretty much can now replace all the steel lines on the truck for anywhere from $50 (1 roll of 1/4 and 1 roll of 5/16) to $100 (previous rolls x2) total.
Want to get her all done before winter.
