I rerouted mine first too, but after a while of hard driving, I saw the hardlines vibrating out of their plastic holders and the hoses starting to sweat around the banjo attachments. This happened with NEW hoses in a months time, and already having blewn PAS hoses over a blocked off rear line ( YES I know, H&R, Dinan, say this is no problem but my hoses blew and two German boardmembers experienced the same thing, and I;ve heard of it on an E34 racer in Germany on the Ring, so pretty please, don't tell me again its OK since box-rebadged Steve Dinan says so) . Really, changing the pump is the way to go. Also because you can get rid of tons of excess SLS stuff
I had them originally blocked at the accumulators, but have since removed everything all the way to the pump and have the pressure line running straight back to the reservoir tank.fficeffice" />
Will this set up blow too form high line pressure?
This is what I did Spending a week with my ///Mistress
I know this thread is old but I am currently going through this same problem. I would like to offer my experience and see of there are any new discoveries.
It all started when we noticed a major p/s leak from that I though was the steering pressure line. It turns our the sls pressure line was leaking too/all along. So without researching the matter first, I block off the sls port right at the pump. Bad idea. The car didn't even make it off the lift before the pump sprung a major leak. I presume this is caused by increased pressure for that part of the pump. So my second option was an alternative pump. The only one available to me at the time was a ZF, dual vane pump without the sls port. The brackets turned out to work just fine, however I need a slightly bigger belt for me to test it and see if it works.
For my swap into my e30, I just put a flywheel bolts in the sls hole. I haven't driven it yet but am I to assume this is a poor solution that will soon destroy my pump?

Just use the standard E34 535 single vane pump, 535 lines.
Works fine, despite what some say. You use the original dual vane pulley, use the 535 high pressure line, reservoir, and the low pressure pump side fitting/modified with new OEL to get some extra length.
I've had this running on two cars for a year or so now. I run both of mine on ATF instead of pentosin. Here's a pic of the first install:
the brackets don't line up on any other pump and the other pump's own brackets don't fit S38
Don't be foolish and tell me the brackets will fit, since they will move the pump out of bounds from the pulley. And the pulley shaft housing prohibits any other bracket then S38 to go on.
I paid 80 euros and shipping for f%ck sake because someone on here assured me any M30 pump would fit, so you can go f%ck off if you try to tell me anything again without having tested it IN REAL LIFE.
Yeah...your pretty much an e-douche aren't ya.

Thanks...I figured as much. After all, It's just a M30 block. I'm going to give that a whirl.
I found out on Sunday that you will also need different hoses for the 735/535 pump so I am going to modify my factory pump instead. There is a nice write up with pictures on the first page of threads right now. This will make it so I don't have to buy another set of hoses (just got all the standard m5 hoses). Sebring may come across as e-douche however he does tend to know what he is talking about. In this case, had my SLS not been deleted already by PO, it would have made life a bit easier and more cost effective to just repair the SLS. Now it is another domino project to make everything work correctly without the SLS. Such is life though. I just can't wait to get the car back on te road and take it for a much needed drive.
What power steering pump do you use when you eliminate the self leveling on a S38B36? For my application (e30 m3) I don't have the self leveling rear and need to source the correct pump to use.
Thanks!
Recently swapped my cracked pump on my non-self-levelling M5 with one that was kicking around the workshop (E36 M3) . Used the M5 bracket and it's working fine.
So there are two people who have successfully installed a 535i pump without bracket modification, and one is running e36 M3 pump with the M5 bracket? I am about to buy a 535 pump for use in my e30 because my M5 pump is toast but am just trying to confirm that people in the states at least claim it is a straight plug and play swap other than needing M30 hydraulic lines to reach (which I won't need for my application) and using the M5's pulley.
Wout, in your initial thread when buying the 535 pump yourself, it sounds like it can be used if you use just 2 of the 4 attachment points. To those who are using it, are those two points enough?
kalevera inspired me to try the 535i pump. Guess what? It works! As he said, just use the M5's brackets (they DO mount right onto the 535i unit) and either bend the lines or get the 535i lines since the connections are now top and side rather than side and bottom. As a bonus, the 535i unit is 4 lb lighter than the 9lb SLS unit. I am using the s14 ps belt which is 10x865mm but you can use +/- 10mm length easily. I am also using the 535i's pulley which obviously lines up straight with the engine pulley but I do see why you couldn't use the M5's pulley if your second hand 535i pump doesn't come with one.
The only item that you could customize if you want is the 3" spacer that supports between the brackets surrounding the adjuster. You'd need to shorten it a half inch or so but neither kalevera nor I use it.
Those with a keen eye will note I have also switched to the 140amp 535i alternator which has the cooling duct at the top rather than bottom which gave me more space to run lines, and makes more sense for keeping road grime out of it (which killed my s38 alt).
