Ok, so what i have done to remove the LONG power steering return line is as follows.
On a LHD car the PAS return line, leaves the steering rack and comes to the front of the engine into the hard lines to be "cooled"
Then it flow back over the gearbox, half way up the firewall, across the firewall, down the other side of the firewall, then back up to the PAS reservoir, as you can see in the diagram below. I have NO idea why the PAS lines flows right past the back of the turbo and down pipe after it has been through the "cooling" stage. Its kind of pointless.
These are the best pictures I could get from my mates TT,
Here you can see it come up the firewall, across and down again.
Here it is again coming back up to the reservoir. Most of the return line is hard line, except where is comes back up to the reservoir. It changes into a rubber hose thats crimped to the hardline, which is covered with heat wrap.
Now on a top mount turbo, the downpipe gets real close to this rubber hose. So lots of heat shield is needed.
My mates BT TT, split the rubber hose, squirted PAS fluid all over the DP and caught FIRE.
So a last minute decision, before the engine went back in, was to remove the pipe that runs across the firewall. After having a look at the routing of the PAS lines. I decided to remove as much of it as possible.
The idea was to have the reservoir relocated to the gearbox side, so I went ahead a cut the lines out.
What I removed is the RED lines in the below diagram, the GREEN line is pressurized from the PAS pump to the steering rack. When it leaves the steering rack, its comes over the gearbox and into the "cooling" section.
FYI - the high pressure PAS line ( green line ) is the one that is bolted to the gearbox. The "cooling" line is bolted to the boost pipe to join the 2x stock SMIC's
As the PAS line comes over the gearbox, there is a short section of rubber hose that joints it to the "cooling" line.
I cut this rubber hose and remove the "cooling" line along with the LONG piece that goes back over the gearbox, up, across, down and up the firewall.
This is the "cooling" line. Its the one that gets attached to the boost pipe that joins the 2 stock SIMc's
So with the PAS reservoir cabled tied between the air filter and TB, I was able to reuse some of the hoses and hard lines to make a temporary solution till the new Vertical PAS reservoir arrives and I can sort out a mounting spot and get the AN fittings done.
