Explorer PS pump not enough with 351W serp setup and hydroboost

[guidoverduci]

My current setup is 351W with hydroboost and explorer front dress. I have the stock explorer power steering pump. It works decent when RPMs are 1500+, but not so much when idle. I’m thinking it’s just not enough to move the 35s. I’ve read about saginaw pumps being the answer. Is there a recommended kit or pump / bracket setup that works with my setup? No A/C.

Anyone have input on single or dual return Saginaw pump? I currently have hydroboost w/ it teed into box and pump.

I'd definitely go for a dual return pump.

Lee power steering can hop up the explorer pump to flow better, or you can switch to TC pump as well.

Unfortunately as of a few years ago, Lee stopped modding the stock Explorer pumps. Their kit now uses the CBR pump (very similar to the TC pump).

IMO CBR pumps are the right fix. They can out flow the mighty Saginaw.

I count myself lucky.

The Explorer pump that runs my steering and hydroboost, 35" tires etc, came from an unknown junkyard source in the Seattle area around 2005, after which I installed it as part of an Explorer front dress swap. Lord knows how many miles were on it at the time. I've added around 150k. It refuses to die and unfailingly continues to run the steering and brakes even at low idle in all the terrain (arguably fairly mild these days) that I throw at it.

Those Explorer pumps, they don't get no respect.

For sure, like Rodney Dangerfield!

Can also get overdrive pulley to spin it a bit fastet.

I wonder if this might be one of the cases where the adaptor that screws into the pump is a hair too long and slightly opening the bypass? Just enough that idle sucks, but at RPM it's fine.

^^^ Had forgotten about that little issue. The bypass is located by the adapter that screws into the output port. There is an inexpensive aftermarket AN6 adapter fitting that fits the port but messes the depth position up- people use it, pump doesn't work, they reject the pump when the real problem was the fitting.

Lee Power Steering used to sell an adapter fitting that sets the depth correctly. That's what I've had on mine since I installed it. Found out the hard way helping others how critical that is.

We should still have our adapter in stock as well. It’s never caused a problem that I’m aware of.

When you say “adapter” are you saying the aluminum washer they sell?

 

[Broncobowsher]

No. The fitting that screws into the pump and gives you an AN-6 male fitting that you attach your custom hoses to.
