Percolation? Heat soak? Don't drive during summer??

So... good news and bad news... maybe bad news???

I just drove the car for about 30-35 minutes, after letting it warm up for 5-10 minutes (it usually dies before then)... The car didn't die, thats good news right?

Most of the driving was stop and go, also pretty slow around the neighborhood and then up and down the street in front of the neighborhood, only romped on the gas a couple of times. The car stayed around 205-208* which I dont like. When I parked it and let it idle before shutting it off the car started getting up there in temp.

Here is a picture of the local weather and the mechanical guage that is hooked up to my intake manifold. (Maybe it gets a little radiation heat from that too?) My guage in the dash wasn't to bad, but some people say thats not accurate.

Also my fuel pressure guage picture and a picture of the new fuel filter. Its just the spectre one while waiting for the wix to come in... the fuel pressure guage read right about 6.7-6.8 psi before driving around, then at 5 psi when i stopped to check it while driving around...

The carb, fuel line and everything is much hotter today after driving it than it was yesterday but the car didn't give me any problems at all...

Is it all possible the water temp gauge is bad or reading wrong? Maybe the sensor is bad it placed wrong?
