Got my new steroid driven power steering pump from AGR and put it on. Followed their directions on the priming and blew a low pressure hose up, painting half my property with the pink stuff :eek:

QUESTION: Anyone know which port on the pump is the high and which is the low pressure? Seems obvious to me that the one coming out of the side of the plastic reservoir is the "low" and the one coming out of the top of the pump body near the pully is the "high". I know I have the box plumbed right since I am just changing pumps. Any help would be appreciated.

Can anyone help? Something isn't right because the low pressure system keeps blowing up and I haven't even started the engine yet. I am still just turning the wheels lock-to-lock with the pitman arm disconnected. I did take the coil wire loose and turn it over a few cranks. That's when I got the real eruption on the return line to the reservoir.

George-look at the PDF instructions on their site, there are some pictures of what I was describing on my IH. The hp should be on the back, near the bottom in the center. The other is the low.

Thanks buddy, but that isn't at all what my pump looks like. I have a top port and a side port. The Saginaw pump in my Ford looks like what you are talking about with two ports out the back, but the new pump is plumbed totally different.

Any other ideas?? I need to go wheelin guys :( Pleaseeeee :D

The pressure port usually is threaded while the low pressure port is just a hose clamp. That not the case?

Thanks Mike, you are right, but in this case the reservoir as well as the pump body both have threaded 6AN high pressure fittings. I know, it is kinds strange and was the thing that was throwing me. I confirmed with Spidertrax and AGR that I have it plumbed correctly. The only thing we can think of is a blocked low pressure line somehow :confused: Otherwise, the line could not buildup pressure and would just flow back into the reservoir. Makes sense, but all the lines are the same and were working when I took the old pump off. I'll check the reservoir penetration itself to be sure they punched out the coupon when I get home tonight.

Or I could put high pressure hose on everything, start the engine, and keep replacing things that break until the system works.......... :rasta:

UPDATE: Found the problem. The low pressure return port into the reservoir was plugged with a bunch of epoxy they used to seal the penetration. Drilled it out and WALLA!
