Got this PM:
"Doug, Reading your offer to show Veggiefuel some tips/tricks for metal lines.. Care to share them with me too?Thanks"
JIC fittings are like any other compression fitting and steel or copper lines can be fitted to them just as easy as you would any other type of fitting. The trick to working with steel is to heat the line up as you do a flare.
The metal work hardens very easy so start your flare heat the metal and allow it to cool then flair again. The angle of the flare is different so using a standard flare tool will not work ( but might be OK to start a flare ).
I use the fittings themselves I hold the nut in a vice and tap the line the cone to stretch the line is the tapered end of another fitting ground on a grinder so it slides into the nut....
How do I keep the line from crushing?
Find a piece of copper wirte that will fit into the steel line so you can exert some presure in out without crushing it ( works good for shaping steel lines as well ).
You can also silver solder things to the steel line to make for an example an emergency repair.
The thing is you need to play with it to figuere out how to shape and formn the lines and its usualy easier to start by using copper.
You can make just about any line you like this way but you need to tinker and practice.
For a box of doughnuts most hydraulic shops will let you have just about all the scrap fitting you like to practice with and most autoparts places will have different size steel lines to practice on.
Word of warning these home made lines are not rated for high presure injection systems. That does nt mean they would work but you are responsible for your own safety.
So get some lines, fittings and ( JIC, Banjo ect ) and experiement. One side note copper is much easier to wirk with but some feel this is not the best material for fuel lines.
