Hello all. I have a new-to-me 2011 5.0 and it has a hot start issue.

Every other hot start or so, it will long crank before starting. Cycling the fuel pump doesn't seem to make a difference. From the little I've seen, it may be a faulty check valve allowing the fuel to boil in the rails.

Hot idle hunts for rpm just a little too. Maybe ±50 rpm

Otherwise the car is great and doesn't show any other issues

Any ideas?
