Default PS Hose Routing

Been thrutching around under the GT trying to get the rebuilt PS hoses back into their "proper" location.

Why does the High pressure hose (Pump to Rack) have the big curve up and over the front strut tower ?

There is much more clearance if it doesn't have to pass by the side of the head.

I would be tempted for the next one I rebuild to modify the hose fittings so that a shorter flexi section routing goes from the hard line coming up from the X member in a straight line to the pump connection

Is there a good reason not to do this ?

As currently installed (may well refine this with more time)

the reason that this hose is routed the way it is, is because otherwise it will run next to the left exhaust manifold, and thats not a good thing for a rubber hose.
The best thing to do in my opinion is get the hard line out and have the hose shop replace the flexible parts with new pieces and also to install a heat resistent cover over the top looped part, also note that there is a hose restriction on the top portion of the loop, try to get this part on if you can

Flexi in the photos is all new but probably not obvious. There was no restrictor in the old hose but may have been replaced previously.

The vertical leg of the flexi passes reasonably close to No5 exhaust manifold connection but that is unavoidable - I take your point that exposing more of it to more manifold would be a bad thing.

at this point you might consider taking some hi heat silicone/fiberglass heat resistant wrap and putting it around the rubber part of the hose , i did this on my car except that i put the heat wrap on before installing the hose, also note that the rubber bumper is not rubbing against the shock tower make sure the hose is not rubbing on any other parts otherwise it will wear through in short order

Hi Jon - to paraphrase your amusing reply to another rennlister on another topic: "Because it can be, and if it wasn't like that we wouldn't need rennlist".

The guy who redid my power steering hoses said that often people use the wrong type of hose with steel braid inside, thinking that is better. He went on to say that if steel braided hose is used and if the engine is not 'perfectly' earthed, then the power steering lines can carry current and this current will reduce the life of the hoses. Just a thought.

Cheers

Dave

Jon,
Change of topic, but what was the conclusion of the rebushing of your upper A arms ?

John

One side is done - GT will be back on it's wheels tonite to get re-registered tommorow hopefully then will get shocks and springs from the SE transferred to it.

So it will be while longer before I have any conclusions and that is going to be difficult as so much else will have changed.
