Not easy to install on a heavily rusty car. Especially the back rubber line.
QUICK6, My 87GN is low mile and totally rust free, yet the rear flex line had "seized" to the hard line, over the rear axle.
By the time I got the rubber line off, the hard line (that runs from rear axle to Combi valve) was mangled and I had to replace it. Not the easiest job to do
If removing the rear rubber line, I'd advise :
1) soak the fittings with PB Blaster, *much* more effective than Liq Wrench, I think.
2) use only a 6-sided flare nut wrench, 12-point will likely slip & round off the inverted flare nut.
3) you may still need to apply heat to the fitting if it's frozen tight, eg a portable MAPP torch. You're working near a bomb (the gas tank), be Careful !!
4) when re-assembling, put a small bit of anti-seize on the threads of the flare nut (but careful not to let it get inside the brake line).
