Power Rack & Pinion Problem

Help!!!!!!!!:HMMM:
I have a problem. I am building a 38` Chevy P/U for someone else and it was brought to me with some stuff already done,namely the steering.
Had it running for the first time today and all was fine till I turned the steering wheel!!!:eek:
It took it out of my hand and went full left then right and continued to go back and forth VIOLENTLY till I shut it off. Started it back up and held onto the wheel to hold it and it blew the hi-presure line. What a MESS.:CRY:
It has a GM powersteering pump and Ford rack.
Any ideas? Where do I start?

You need a pressure reducer, Flaming River and a number of other companies sell them....When you get it installed, bleed the unit and try again...

The GM pump should be a saginaw pump, and it does produce more pressure than the Ford pumps which could be a Ford/Thompson or maybe a Eaton pump. However Ford did use some GM Saginaw pumps on some of the Mustangs in the 70's as well as on some of there cars with Racks, so this probably isn't your problem. There is a pressure relief valve inside the Pressure line on the Saginaw's pumps and this can be changed to change the pressure. Hopwever with that said from what you state this system did your problems lays somewhere else besides pressure. Sounds like you need to diagnose this "Self Steering" problem first.

Might be possesed by demons..Need to get in the yellow pages and find an excorcist!!!!!!!!! I've seen them go to lock like that but never back and forth and not blowing the high side line like that.Almost has to be a stuck valve or lack of a required regulator. Everyone used saginaw pumps, GM ,Ford, And Chrysler.

Your pressure and return hoses are switched................

The hoses on backwards occured to me also today,I will check that later.
It makes sense,because the brakes did`nt work right either he had them plumbed backwards also!!!!!!!!!!!:LOL::whacked:

Repaired and swapped the hoses,FIXED works fine!!!!!!!!!;)
Thanks EVERYBODY:D
