GM steering pump with full hydro

85toyo · Aug 2, 2012

I've been searching for a while now with no results. I want to use the stock steering pump that came on my motor for full hydro but it has a built on reservoir. I've heard it's been done but never seen it personally. Does the stock reservoir hold enough fluid or does a second reservoir need to be added?

That is what I am using with a DE cylinder.

I run a stock pump turned up with a hydro hose for extra fluid capacity seems to work fine ... :dblthumb:

Just run a good cooler an you will be fine.

Thanks for the input. I thought it would work but I want it to be done right the first time so I thought I would check here first.

This is on of many instances where a double ended ram is better. The system fluid volume remains constant whereas with a single ended ram the fluid volume changes depending on which way the tires are pointing.

I had planned on using a single end but haven't decided yet. That's why I was wondering about the fluid capacity.

One direction will fill the reserve the other direction will suck it out. It will work but for a little insurance try to rig up some kind or reserve, and make sure to run a cooler.

Figured it out finally. Drill and tap the side of the excisting reservoir on the pump then run a line up to a second reservoir. This will keep enough fluid in the lower reservoir while the single end cylinder is at full stroke.

Will the canister attached to the pump work. Sure.

Drill and tap the side of the reservoir? Good luck on that , the reservoir is thin and I don't believe you can tap it.

A better choice would be to run a remote reservoir set up. You will be glad to have the extra volume to hold extra fluid . This is helpful both in terms of feeding the pump and allowing for the uneven displacement. If you have modded the pump's ability to flow more fluid you will really want that extra fluid. A modded pump can starve and cavitate quickly.

Take your existing pump out of the can and order up a reservoir can from psc http://www.pscmotorsports.com/remote-fill-p-pump-reservoir-can-12-jic-feed-oring-side.html

Place your p pump in one of these cans. Then fab yourself a reservoir or purchase one of your choice. Try and locate your reservoir as close as possible to the pump. Mine mounts directly over the top of the pump with a 3 inch long piece of size 12 push lock VACUUM RATED hose connecting the reservoir to the pump. If you have questions feel free to pm me. Good luck on your endeavor.

That's good to know. I wasn't aware that they sold those. The original plan was to buy a PSC kit without the pump to save a little cash but now I can't find a single end kit without a pump, only a double end. Looks like I'll just get the whole kit and save myself some time.

I don't know where your located but I have a brand spanking new Psc pump I'm not going to use I could hook you up on!

And save yourself some money and just get a tsc ram. You can't beat them for the price

I run a GM Pump of an 87 G30 Diesel Van. Same P pump but instead of having a reservoir with cap has nipple to run a external resevoir. Have knot had any problems with it running a single ended ram.
