Doing the 2wd box swap for my crossover. Got a rebuilt one from the correct one from the same era 2wd truck (Mine is a 1990). Pulled mine and noticed that only one hose had an o-ring that was actually still stuck in the old box. I used a small pick to remove it just to make sure it was in there. It was on the hose end fitting that was closest to the engine. The one closest to the drivers side fender did not have one.

Is this correct? Should only one fitting have one or was I missing one? IIRC, the last time I did the same swap on my burb, the rebuilt pump came with two o-rings but I can't remember for sure.

If I do need two new ones, anyone know where I can get them? I cant seem to find any actual kits with new o-rings on the interweb... Thanks folks.
 
Ok looks like the 1.5mm x 8mm ID may be correct. Can anyone confirm? Thanks
