Any suggestions on removing & replacing would be appreciated
Should I roll the engine forward for better access?

Whole line or part of it?

Whole line,it'* the steel hydraulic line so that is under a lot of pressure from what I have heard.

Best way, is to break it up into sections(so cut the lines out in sections)........approx. copy the bends, and connect with unions......the fitting on the BPMV will be different and probably be reused......you will need a tool to make bubble flares....you MUST NOT use compression fittings!

You will have to properly bleed the system to get rid of all the air....

if you are replacing the whole line it doesnt matter if you get the old one out. when i do my vehicles i run them up and out of the salt so they last longer and its alot easier to run them were you can get to them. just cut it off at the ends so you can get a good six point socket on the fitting, they have less chance of stripping. then take the fittings to the parts stores and see what you want to do. they have standard to bubble flair adapters, if you dont want to bother with the tool. or you can do like i do, get the tool a handful of fittings and a couple coils of line and replace them all, because normally they all go at the same time. i think the tool was 50 and the rest of the parts were 50 or 60 last time i bought them
