hydro assist.....disappointing

[eripley]

Update. please help me hydroboost gurus!!

Update.

I drove this truck this last weekend. the ram moves very slow and somewhat jerky. It basically doesnt do a think to improve steering. I know hydro boost brakes hinder flow and are restrictive so im pretty sure that is the problem with my setup. hydro rams need good flow and pressure from what i understand.

so my options were:

new racing pump (doesnt really fix the problem of the restictive hydroboost) $160
or
get hydroboost modifed for flow by guy on pirate4x4
$180
or
junkyard pump $25 hose $20 and new belt $11

I chose the last item.
What I did was make a bracket and mount a second power steering pump that is bone stock to power just the hydroboost brakes and the exisitng modified saginaw is going to run the gearbox and ram. This worked good in theory till today when I went to get the hose made to go from bone stock pump to hydroboost. I realized that since there is two high pressure lines and one return on the hydroboost unit. I dont know what to do with the high pressure out line on the hydroboost unit. I was going to cap it but was told at the hydraulic place that if you cap it it will blow the seal.

Sooo...what do I do with the high pressure out that usually goes to the steering gearbox? I like the idea to run dual power steering pumps and have been on that bandwagon ever since. But is there a way to vent off pressure on the high pressure out and return it to the return line?

Basically here is my setup now (or the way I want it)

saginaw pump#1 (modified for flow and pressure) > gearbox > ram

saginaw pump #2 (bone stock) > hydroboost

But hydroboost has the high pressure in and high pressure out and return.

thanks for listening and for your inputs so i can get this truck put back together.

FYI
1.5 chiefmax ram with 42" tires.

I am not familar with the differences between a hydroboost power steering pump and a regular but it sounds like the pump you have has 2 outputs and one return. if thats correct you could always just run 2 regular pumps. my power steering pump only has a high pressure and a return.

no.

The hydroboost itself has the high pressure in and out not the pump.

no.

The hydroboost itself has the high pressure in and out not the pump.

well that certainly rules out my idea. I take it the high pressure from the hydroboost then goes to the steering in the stock setup?

That's correct.

Just turn the line that went to the steering box a return and tee the original return from the hydroboost into that line, problem solved. It will simply just loop the fluid back into the pump all the time just like the steering box does.

I did similar. What you suggest wont work as the high pressure and return wont "T" together as the highpressure will build up in the return line.

i just brazed a second nipple onto my reservoir...or you can buy the hydroboost one.

I ran the high pressure out back to the pump using one nipple and the return using another.

It appears to be working. I need to drive the truck around and see if the steering and brakes improved. i will report back.
