I have a 1998 New Holland 8260 cab tractor and need some help with it, back in the spring I noticed the tractor wasn't starting as easy as it usually does, it had to turn over several times before it would start. Recently I changed the fuel filters and during the bleeding process I noticed the bleed screw was spitting out air like crazy along with the fuel, probably the reason it hasn't been starting as easy. I replaced the 82012602 (Red) fuel line and also the electric pump (87802238) and it is still sucking air somewhere, same amount of air coming out the bleed screw. I let it run several pints of fuel out the bleed screw and the air just kept coming! What else could it be? Anyone else ever had this trouble??
