    John deere 5520 fuel problem

    I have a 2002 john deere 5520 with cab and loader, it has a electric fuel pump that has been added, the local dealer said this is common with this model, i need to replace it and need to know what pressure one to buy, can anyone help on this ? He said that is probably all my problem is.

    Can you describe your issues? As far as the pump, could you just find a part # printed on the current pump and cross it to a new one?

    John Deere 5520 fuel problem

    i could, but i think that may be the issue, it takes a bit to start, when does may not get all rpm that it should, if on a hill it stales, and when gets below half a tank of fuel as well, dealer told me they had a lot of problems with this model and they solved it with the electric in line pump, but could not tell me the pressure, probably because they wanted to do it.

    If you already have a pump installed? You should be able to feel of the pump and tell if it's running, and you can remove the supply line and stick it in a jug and turn on the key to see if it's pumping.

    If it's not pumping check fuses and make sure you have power to connections. Take it off and to a parts store if you find out you need a new one.

    I'd make sure the filters are changed and see how it runs before I did anything.

    I'd suggest to check for good fuel flow from tank & be sure tank is venting. Also check by removing fitting encircled in blue to be sure check ball isn't clogged.

    I think they might be an Airtex pump.

    Remove hose from fuel outlet on fuel tank to determine how large a stream of fuel exits tank. If it's just a dribble then remove fuel cap to see if "no venting" is the problem. If still fuel dribbles out then there must be foreign object inside tank blocking fuel exit. 5520 parts schematic shows an inline fuel filter near tank. Has this filter been changed lately?
