Engine temp...
Enlighten me. The other day I removed a marginal electric fuel pump from my base 350/300/4 spd. and installed a stock mechanical pump. The car performs noticeably better in all areas i.e. starting, acceleration, idling.
The other thing that I noticed and didn't expect was the temperature gauge was indicating a cooler running engine. Would the new fuel pump cause this change and why?

I wonder if your engine was running too lean with the electric pump. Pressure set too low maybe?

Think about this.
ALL the electric fuel pump was doing is providing fuel to the bowl of the carb...where the accelerator pump and jets give fuel to the engine. This engine is NOT fuel injected....so the electric fuel pump has nothing to do with this....it can't. Due to the needle and seat...which stops any more fuel being added in the bowl when the float is up where it is set at.
And if it were fuel starvation...because the fuel pump was NOT supplying enough fuel...then when the car was ran hard...the fuel in the bowl would get used up and the car would begin to die or act like it was going to die.
Just my 'take' on this.

I did want to thank you for an old post that you'd had written. Last week I let my Grandkids play drivers in the car while at a cruise in. On the way home I had non working wipers. I checked 'everything' I thought until your post reminded me of the 'radio ****' under the steering wheel. Yes sir the kids must have turned it off - I turned it on whal la working wipers. I don't know why I forgot about that switch but thanks for reminding me as it ended my frustrating troubleshooting.
