I have a 03 ford 6.0 i installed the airdogg2 165 gph and runs great must of time but it seem like if it around 1/4 tank i start to lose fuel pressure if i really get into it. My gauge will read 0 and it sometimes takes a sec or two, to get pressure back. i know something isnt right and i dont think this is good on my pump or injectors. Also what is a good fuel pressure to run. Its set to 60 psi at my gauge.????????????
