Replace fuel lines or add filter?
When i disconnected the rubber line from my fuel tank to the metal fuel line that runs along the side of the frame rail to the engine, a little bit of gas came out of the line and was red colored. Looking in the end of the line (cant see much as it immediately bends and is I guess 5/16", it appears to have a little crud but not much.. The fuel feed lines are in 3 sections. the first comes from the tank and runs up the frame towards the front of the van about 7 feet. There it changes over to a rubber line for about 2 feet and then back to metal up to the fuel pump where it has a short piece of rubber hose connecting to the fuel pump. Then you have the metal line that runs from the pump to the carb and filter..
Taking the 2 foot rubber line loose on the frame rail that joins the two longer pieces, there doesn't appear to be any rust in that line...
Should I replace all the lines or do you think I could try adding a filter in the line where the 2 foot rubber hose joins the two metal lines and see what happens?
If i replace the lines should I use stainless steel as it is resistant to ethanol?

Another thought.. If I change all the fuel lines, how do you make that tapered end on the metal fuel lines without a expensive tool?
What do you think about this idea... you can buy steel compression fittings and i was thinking to move the furrow out closer to the end... Once the furrow is compressed on the line I would have the nut to deal with. The first one would be easy to remove the nut as you could slide it off the line before you bend it.. The second on on the other end would require you to cut the nut off.. The furrow would not need to be compressed down too tight as all you are trying to do is use it to make sure the rubber fuel line never slips off the steel line.
If the furrow was a little thick, it could always be ground down ans smoothed off...

No you don't want to double flare stainless. Just do a single flare. If you do a double you'll be much more likely to crack the line.

What angle do you use on brake lines?
Later I plan on replacing the rear brake lines.
I'm guessing the HF tool is 45*

Steel brake lines are a 45 degree double flare. For SS lines it's a 37 degree single flare and requires -AN adapters/fittings.
