Have been investigating a little further and not 100% sure it is well plugs or fuel draining back toward tank. When jwilson645 mentioned original fuel filter that has a check valve, I remembered when I got truck 3 years ago was doing tuneup and gathering parts and auto parts store did not have filter with one. Did not realize at that time it may be critical so got one without. I usually drive several days a week and had not been very noticeable until it sat for 5 days. So, I have ordered check valve for original filter and will see next week if that is the issue. I had purchased an inline check valve and had not installed yet.
