I own a 2008 5325 that is giving me fits with the fuel system. I looked at a couple of the other forums to get some ideas, but still having issues. I changed all the fuel lines, as the system was getting air in it, and the lines were not the best. After making the change to all the lines I bled the system, and I think that I have all the air out of the system, and the tractor started great and was idling fine, and after 5 minutes the engine died, and I opened the bleeder screw and there was no fuel, so pumped it back up, and bled it again. Does anyone have any suggestions, is there a fuel filter somewhere that I might not know about, that is restricting the fuel flow? Also there are two lines that goes from the engine back to the tank, one is a 1/4 and the other is 3/8. can somone advise the differnce in these lines. Thanks for all the help.
