    I just had the fluid changed in the power steering system in my '55 President and there was no filter. Should I be using one?
    Your '55 would have the Saginaw setup. So far as I know there is no "filter". There may be a screen someplace. The '55 setup return hose goes back into the pump body and I am not sure what happens from there. I have a '57 pump on my '53 and those have the return hose going to the reservoir/tank. There is a double layer fine screen inside. I actually had to pull this apart to clean out once when red silicone sealant I used on the cork gaskets under the tank had bits get into the system and clogged up that screen.

          I bought a steering pump set-up from a 390 T-Bird early to mid 60's and it had the same pump and reservoir, I wanted the dipstick lid. Just look for a '65ish or earlier Eaton Ford pump. The shelf for the filter is held on by the bolt that holds the housing to the pump.
