Hi Folks,
I cleaned one of the short oil pipes in my machine with kerosene and a small brush that I was running the entire length of pipe, it took about 10 passes back and and forth to clean it and still everytime I pass the brush it still come out a little bit dirty (perhaps is just the brush that does not clean 100%).
I decided I am just going to replace the copper pipes with new ones. I have nylon pipe left over from when I replaced the nylon lines, could I use nylon instead of copper or should I just order the copper lines? Thank you!
