To best of my knowledge the only non steel line is the hi pressure hose under the resevour.
I've read that some people unbolt the controller to allow a little extra wiggle room when changing the accumulators. I had my inde maniac do mine because I didn't have the strength to loosen the banjo bolt feed to accumulator.
Also be very careful with reattaching lines into controller. I read that they are very easy to strip.
Once the weather warms up we should do a measure survey. "What's the distance from Star [axel] center to fender lip, left & right, front and back."
