I switched it to copper line so i could avoid the header problem with it again, still had the same problem realized that copper line is super easy to pinch so I just decided to go to an electrical sensor so now I have the pressure sensor directly plumbed in to the block with no risk of kinks and even the electrical gauge doing same thing! before i put it in I just cranked it over with no line or anything there and oil just gushed out just cranking didn't start it though.
