    I just replaced seal in ps pump and installed, and yes I have adapter coupler installed (new one, old one mysteriously vanished) and nothing yet. I'm guessing it needs to be primed/bled. I have front end jack up and keep turning but nothing for hours.

    Did you crack open lines at steering box with eng. off and wait for p/s fluid to come out?

    Are you getting p/s oil running out of line at steering box with motor off?

    Yes the big line it runs out like crazy by pump and reservoir runs to it directly. Filters to or from steering box. I need to get more fluid because I kicked the container over by accident. You would think when I crack smaller line it should leak like crazy from pressure but isn't. Hope I don't have to take pump back off.

    I took pump back off and frustrated af. I took pump apart again and determined I must not have it back together right but I have no idea how to fix it.

    Lay it out and send pictures. Best to mark everything before disassembly.

    Thanks for all the help. I studied witness marks on parts and got it work.

    The parts whisperer, fixing trucks based on previous scrapes and marks.

    If you have it together maybe you can write out a note reminding thsoe of us who may have forgotten or possibly teaching those of us who escaped from kindergarden to try and play with the big kids without knowing how. +)
