Help with 2640 Deere!

[Got Smoke?]

Ok 3 weeks ago I promised my girl a ride around the edge's of our property. The best way to get around in those woods is the 'ol John Deere. Well I went and got it that morning, started it up, moved it about 10ft. , and was setting the bushhog down to disconnect when she just died!:--)



Well after Dad and I got to looking at it it ended up being water-in-fuel.



So new we have drained the tank and added a new fuel filter, but now it won't get fuel back up to the filter!:{



We have tried the primer and it just laughs at us. We are totally lost on what to do



We loosened the line at the primer, but it doesn't even get fuel all the way to the primer. The fuel line runs directly from the tank to the primer then to the filter. Well its just not moving away from the tank?!?! Any idea's cause we really need to get the Deere running again!

If you are near a compressed air source, take the fuel cap off, loosen the fuel line at the transfer pump, wrap a rag around the air nozzle and CAREFULLY apply air pressure to the tank. Be careful not to put too much pressure to the tank. I used to do this on Diesel VW's as they had no transfer pump. Before you pressurize the tank, you might "back blow" the fuel line going to the tank to make sure that it is clear. Take the fuel cap off when doing this also. I'm sure that you will have to bleed the high pressure side of the injectors off too. To get a faster bleed on the high side, I put the throttle in the wide open position as this will deliver more fuel to the injectors. Good luck, Chris

I would blow from the transfer pump towards the tank to clear the line. There is probably gunk in the tank plugging the outlet. Most likely it will gravity flow after it's unplugged. It will probably happen again until you pull the tank and flush it out.

Look in the tank with a flashlight - maybe some neighborhood delinquent put a handful of mud or something in the tank. We've had that happen.



I know you run your tractor often, but I once fought and fought with the fuel line on an old antique Cat 10. Wasps had gotten into the tank years ago and pieces was wasps were plug the fuel line now and then - and they don't dissolve in gasoline



I'm sure you'll find what is wrong with your machine.

Yeah dad's about set to take the tank off and start over from there. We are going to try the compressed air trick first though. If that doesn't work then its time to break out the wrenches.



Thanks guys!
