I agree about Earl's or aeroquip line

We bought a line cutting tool__Looks like a bush trimmer-- cuts the line perfectly without leaving any residue in the line to clean out--it is easy to use in place as you plumb a vehicle so it is easy to cut the correct length and clock the fittings in place as you go--cutter looks like a cable cutter but has longer handles--no tape needed

I'll try to find a current source
