3306 Cat, probably been asked lots
What are these engines like? i have heard the 3406 was junk, and i have heard the same stuff about the 3306. We got a tractor right now we haven't used yet, with 8000 hours on it. It seems to run fine, but we don't know if it uses oil or not yet, haven't ran it much yet. It wont start on its own though, always needs a bit of either first start of the day. The fuel filter housing seems to be leaking down and air is getting inside, and even if you prime it she wont fire.
I know for a fact the fuel line is sucking air in, but i have heard that they can be that bad to start normally, and that some people even put lift pumps inline to help them start.
Would this be a good idea to do while im changing the line tomorrow? or should i just change the line and leave it. Might be some seals i was thinking in the primer gone, or the filter somewhere up there. This is in a PT 270 , 1978 i think
