Great ! thanks fellas. I have used and still do on 1 truck copper lines.
They work the best ..unless you have to move it around any. I might say there is different quality lines offered.
I`ve had to pull the cluster on mine enough to weaken the copper. specially at the fitting.
So the clear tube works for now as long as I don`t think too much about it. LOL
I know visually this engine oil is being moved up and down.
