V8-250 Saloon - PAS Reservoir Hoses

Post by classiclife » Mon Dec 03, 2018 10:28 pm

Hello,

Investigating some PAS fluid leak, I think I have narrowed it down to one of the 2x hoses that come down from the PAS reservoir.

Checking SNG & DMG website I note they do not list these 2x hoses.

As such, what is the accepted type of hose to use on replacing both of them, please ?? The fact the hoses are secured by Jubilee clips this suggests a hose able to handle low pressure will suffice, but I would like to check before making any decisions.

I'm pleased to say that SNG does stock the high pressure hose between the PAS pump and steering box.

Thank you in advance for any advice.

Regards.

Richard.

if you have a hydraulics supply place nearby you could try them... both the hoses from reservoir ( one feed to pump.. other return from box ) are low pressure lines.. but they have specific a fitting at steering box end, which can be removed from old hose and re-used ..

Hello,

Further investigation has now identified the issue, there is a leak from the high pressure (HP) hose between the pump and box; to be specific close to the reservoir. That gave the impression one of the reservoir pipes was leaking but that is not the case.

A replacement HP hose from SNG was the answer - but actually no. Although the pipe was listed on their website, they had failed to remove the details as they no longer stock the item.

No problem, because DMG stock them.

All was looking good until I told them my steering box has a female connection, as my original HP hose has male connectors at each end. The upshot is that the HP hose that DMG supplies is only suitable for steering boxes with a male connector - which is shown clearly in the parts manual. In fact the DMG advisory notes state their hose is only suitable for steering boxes with a male end.

My only option is to have one made by a hydraulic company, but I will have to resuse the metal pipe section that goes to the steering box as there is an acute bend prior to the male coupling and the hydraulic company cannot replicate that.

The issue will be resolved, but it has been a real "around the houses brain teaser" to determine a suitable answer.

It is an odd one really, as I was unaware that the steering boxes fitted to these cars may have differing receiving ends - male or female.

If anyone has any input re the issue, please let me know - many thanks.

Regards.

Richard.

Richard.. you could replace the internal end fitting into steering box with banjo bolt and 90o or 75o fitting (whichever will work/fit best in situ) at the steering box end.. as long as you have the male end for thread patten, a hydraulic supply house should be able to fabricate this for you.. banjo fitting with 2 sealing washers tends to be superior in sealing than an internal flare fitting of the type used either end of the high pressure line..(the famale hose end more common on box end seals better) the pump end is notoriously prone to leaks.. often requiring a tapered seat washer to seal..
