Re: Oil pressure problems, maybe.

Great info as always especially on where to mount an additional oil pressure sense line.
I'm concluding from this post that two independent things happened last week (odd to believe they are coincidences but sometimes that really happens, I guess):
1. oil pressure problem caused either by flaky pump or sludge intermittently clogging up oil pump pickup.
2. Fuel flow problem due to possible weak fuel pump and/or vapor lock onset.
Regarding the Oil pressure problem, I have been meaning to change the oil. But as long as I was doing that I wanted to drop the pan to clean it up. As long as the pan was off I want to replace the oil pump with the Vines solution. I have hesitated doing this because I'm now thinking of pulling the engine so I can clean up the firewall and other hard to reach places on the body and the engine as well as repaint the engine back to ivory etc etc etc. If I do that, replacing the oil pump and adding another oil press sensor will be much easier(and I haven't pulled the engine because I need to drive the car to get my hood fitted and need to do drive it again on Friday.)... So once I get my hood back on, I'm going to take it off and pull the engine and start this process (assuming pulling/reinstalling the engine is relatively straight forward).
Regarding the fuel flow problem. I have not experienced what I consider to be classic vapor lock (car not starting after running etc). BUT I do think I either have a fuel pump problem or a fuel line issue. When I first installed this plastic fuel filter (replaced a PO metal one) the fuel level (at idle) was fairly high at the exit side although the element was probably more than half out of the gasoline. Now you can see the gas level is very low and just dribbling down the inlet side. The downstream glass bowl filter housing is always full though. SO maybe while my engine is out I will rebuild (or have rebuilt) the fuel pump. I'll also consider adding a pulse type fuel pump near the tank as per Howard's suggestion.
Thanks for help, guys. Any words of wisdom or caution on pulling the engine would be appreciated.
