Little update on Earl..... I have gotten used to running him every or every other day. I had a new issue today. We had 90+ degree heat today and when I went to start after sitting all day outside, it wouldn't without a little shot down the throat. Ran ok but a little rough. I had one stop on the way home and then it just quit like not getting any fuel at all. When I put a shot down the throat, it would run for just a few seconds... Im thinking vapor lock.
Now the configuration of fuel line is as follows... Hard line from the back to a soft hose (new) and it actually had a little downward loop in it routing up and to a fuel filter ( also new). New line to fuel pump. I was thinking that the fuel filter might be my bottle neck so I removed it and went direct route from hard line to the fuel filter. Put another shot down the throat and it ran perfectly.
My problem had to be in the filter or the loop that the line had made to get around to the pump. Now the question, is the filter sock in the tank sufficient or do I need a filter before the pump. There is not one between the pump and carb as I don't know how to plumb that in since it is hard line all the way. The truck ran fine with the mechanical pump so I really don't want the hassle of doing an electric unless completely necessary.
Thoughts.

If you add or switch to an electric pump, you must run a filter into it.

Thanks.... PapaBear I appreciate the comment. I will leave the fuel filter off before the pump. Do you know of a way to plumb in the filter after the pump as I do not necessarily want to cut and flare the hard line.

Remove the hard line, get a male thread x hose barb adapter and run a hose up the front. Plumb in the filter where convenient. Use EFI rated hose.
Or...braided steel hose and AN fittings look cool, too $$$$
