I have a 94 ps 7.3 turbo. I am getting alot of air mixed with my fuel comeing from the steel braided fuel line that comes off the front of the drivers side head to the fuel filter. I have put clear lines on to find out where the air is comeing from. I have no air comeing from the pump going to the filter. I have alot of air mixed with the fuel on the line that goes back to the tank. I took off both of my high pressure return lines where they connect back to the filter and noticed that the drivers side return had alot of air mixed with the fuel. If I start the truck it will run till enough air builds up and then it will die. I can keep bleeding the air and it will run all day. I have replaced all my rubber hoses so far. any ideas on where to go from here????
