Explorer serp tech help

I am trying to wrap my head around this power steering pump system.

I have a 4x4x2 box (previous owner installed) and I have it adapted to -6AN male with a 90 degree fitting (also from the PO so I don’t know where it came from) so that end is good to go.

I had my local shop make me a high pressure line with -6AN females on each end.

I have the Russell 16mm to -6AN male adapter from Summit on the pump.

I cannot seem to find a 90 degree fitting to go from the male fitting on the pump to the female fitting on the hose that isn’t made of aluminum, like these. I need to turn off the top of the pump to head down towards the box.



Can I use aluminum safely? Does anyone know of a steel version?

Here are the fittings I scavenged from the old pressure hose. The 45 degree bent one that says pump is what I need to replace.

Tom Lee (of Lee Power Steering) has stated that the 90 degree fittings like that blue one restrict the flow too much and should not be used.
The ones with the tubing bent in a curve do not restrict the flow.

Yup, you need sweep style 90ís. And they need to be steel. PS pumps can produce over 1500 psi, those aluminum fittings arenít up to holding that kind of pressure.

I have dug through pages and pages of Summit fittings and haven't found anything like that. Weird.

edit: well, ones that aren't a hose end. My hose is already terminated with -6 females. Maybe I need to scrap it and just make my own hose.

Is the tight 90į fitting flow an issue on the return?I added the bc fluid cooler and I think it came with a tight o0.

We have these kits (#2053 and #2081 on this page: https://www.wildhorses4x4.com/catego...csteeringparts) for rolling your own.
All you need are the adapter fittings to whatever pump and box you're using.

This is the way to go, and the prices are competitive with most any other place online.

You will probably have pressure issues. The Explorer pump is well known for being finiky about the adaptor that is screwed into it. The adaptor from Lee's Power steering works, most others do not. They hold the relief valve open so no pressure can ever build or something like that.

Full throttle, it either solves the problem or ends the suspense.

I believe mine is the Russell fitting also. I do know it came from Summit. Haven't had any problems. I could just be lucky though. I have heard of there being problems though

I didnít read about those issues until I already had it in hand. At least I will be in the know if it gives me trouble.

I don't remember ever hearing of any issues with our fitting either, but you guys tell me if I missed any.
On this page: https://www.wildhorses4x4.com/catego...eyword=fitting I believe it's the #2068 but I'd have to look it up to be certain.
