I have a 2005 f350 Harley davidson edition with 207k miles that has developed a no start when hot condition once I replaced my tranny. I've read through all of the forums here and tried all the obvious stuff (STC, Dummy Plugs, Stand Pipe) and I blew air through the system and it doesn't leak anymore. But, what I dont understand is that I have to crank for 5-10 seconds when cold to get enough low oil pressure to fill the reservoir for the HPOP. I checked to see if the anti-drain valve was not working, and it was okay. Any thoughts??
