Re: Oil pressure problems, maybe.

So the plot thickens...
I pulled off the existing double action fuel/vac pump and took the fuel section apart. The rubber looks very good and rather new. Unless the spring or other parts are worn, I wouldn't think it would be a problem. There is no name on it anywhere and just a little metal tag with 4293A stamped on it. I haven't been successful in finding a rebuild kit for it yet with limited info. So, I bought a $18.00 Airtex one from Advance Auto (thanks to the Parts X-Ref) to keep me going until I get around to rebuilding the other. That required a little replumbing of the metal fuel line (used a brake line which worked out great) and some of the hoses. I decided to take off the plastic fuel filter and noticed that the inlet side had constricted. See pic below. Don't know if it got too hot or if I overtightened the clamp when I installed it a few months ago. Wonder if that constriction is why the car was straining on overpasses if it was starving the carb. I still had the metal inline one that I replaced and put that back on. It all seems to work.
So still being worried about the intermittent oil pressure drop, I decided to look inside the bypass oil filter. The filter element looked almost new with no oil on it. The only oil was a 1" or so green sludge at the bottom. In looking how to take the unit out, I noticed that tube from the block to the side of the filter housing was NOT connected to the block and a bolt was installed in it's place (hard to see in the mirror shot). No wonder the filter looked new, it wasn't doing anything.
Why would someone disconnect the filter?? This adds a lot of credence to the oil sludge theory of why oil press dropped last week then regained itself, I think.
Any thoughts would be very appreciated.
thx,
Bob
