Thank you for the information, I think I will install the filter in the reservoir and see how that goes, unless someone else provides some insight why I shouldn't.The 68 442 had a filter element in the tank that works fine until the pump veins broke. New pump and new filter all is well.
My 73 has this tank on the pump but still has a filter on the firewall.
53 has no filter at all.
I like the cleaner reservoir design if not putting a spin on. If everything is new and clean just leave instructions for the grandkids to replace 40 years or so!
