I gotcha. Well, I can't see that the reservoir itself makes much of a difference but who knows. I found this one that should mount in the same location but it's shorter so I could get the output higher.

Is your current supply line horizontal from the res to the pump or does it have to go uphill at all?

I did get a response back from my friend. He said high, short, vertical, big are what is needed to supply adequate volume. He ended up building his own res from 3" alum tube and putting his own bungs on it. But with a truggy, he has a lot more options than you.

Before throwing more money at it, I'd look long and hard at what you could do to temporarily raise your res up and try to recreate the issues before. If it seems better, then cut as much of the supply hose out as you can, reattach and see what happens.

The other thing that I think helped me is that the outlet on my reservoir is at a very slight angle rather than vertical.

This eliminates the need for the 90 which as Justin correctly indicated, may cause flow restrictions.

You can see in this one pic the incline...

Airbur, seeing those pics I agree you are on the right track

These are pics of NVRSTK's Bronco. You can see that his reservoir is WAY higher than mine is. He has a 3" body lift and a raised hood.

I'm going to see how far I can raise the reservoir with the hood propped open. Limiting factor will be the return lines as they aren't any longer. I may make some new ones just for this test.

If I can verify a significant difference in performance this way, I'm going to drill a big hole in the hood so the reservoir can stick out!:)

I though about using a small hood vent scoop over the hole, but the location is to close to the main scoop.

I was able to raise the reservoir up about 3" today by just moving some of the hoses. Drove around a bit using the brakes hard and steering at the same time. I didn't notice any issues. The output on the reservoir and the input on the pump are level. So there's my problem. The only way to keep it like this is to cut a hole in the hood:(

Glad you confirmed the diagnosis.

Your kidding about the hole in the hood right ?

How much volume do you think that tank needs to have?I'm going to be doing this sometime in the future and dont want to have to use any body lift.I think it would clear my glass hood,but not sure on a stock hood.

Wild Horses is making a bracket to replace the stock Explorer pump with a Saginaw pump. I think I'd do this before messing with the Explorer PS pump.

Interesting. But it only has 1 return and no AN fittings. Also, something about that install/bracket/doesn't seem as stout as the Explorer's.

Saginaw pumps can be had with 1 or 2 returns. I don't think they are going to be AN though. I'm not sure how stout the brackets need to be. The Saginaw pump has a better reputation than the Explorer pump.

The dual returns on a Sagniaw aren't AN, although you could have someone weld AN fittings on it. Really at that point, you could just mod any Saginaw housing. Now that I think about it, I may need to do that to mine. I've got the WH v-belt Sag bracket. It's plenty stout.

I believe you can swap the rear reservoir on a Saginaw with one that has an fittings. I did it on my full size for my hydro assist. I don't remember who I bought it from but I will look.

Will this work? This is the one I used.

I did some and didn't find anything. Let me know if you do. If nothing else you could pull the housing off a junked car.

I was just reading a thread on CB.com regarding replacing all the Explorer pump internals with internals from a diesel unit? Anyone heard of this? The guys say it's awesome and they don't have any more issues.

the diesel pump probably does flow more but I feel its still not enough. Atleast on my truck. The diesel does have to run hydroboost and steering. Plus it has 1000+ lbs over the front tires.
