Hard start after studs, longer it off longer crank?

Please help, still working on truck, posting from phone. Got it all back together and it took a long time to start. Once running, runs good. Then when I shut it down, the longer it off the longer the crank time to start. If I start immediately after shutdown it starts fine. If I wait 1 min it cranks about 10 sec before start, if I wait more time, the crank only gets longer? I had it off for 15 min and I had to crank it about 20 sec to fire. Any advice. Ran great beside this. Please help.

Never touched the fuel filter, just left it in the assembly when I took out oil stand. I'll check the lines though, those were all apart.

Maybe your stand pipes or dummy plugs are leaking? I would drive it for a bit and work all the air out. Just throwing out ideas
