John Deere 997 Fuel System Diagnostics

Thanks for this video. My 997 had the exact same problem. This will help me clean it myself next time rather than transporting it to the dealer.

You're welcome.

Thanks for this. I have the same issue. I've done some digging and have found I have diesel bug. I'd never heard of it.

Thanks for posting this. I am experiencing the same problem with my JD 997.

Hi so I pulled the fuel pick up tube on the out side of the tank and the screen on it was almost completely plugged its hard to believe the mower would even start at all, I Cleaned it all out and reinstalled the tube. Mower ran like a champ. Thanks for the input it helped.

[@rancher9625]

Yep. Exactly.

youtube to the rescue again - exactly what my problem was - thanks!

Hi great video So my 997R starts, runs and after lets say 5 minutes it'll die down if i stop the deck it'll recover as though its looking for fuel i pumped out all the fuel, changed the screw on filter added diesel cleaner and it's still doing the same thing. is there another filter beside the screw on filter??

I think you missed the two places in the video that it mentions the screen in the tank. Might want to check that if you haven't addressed it.

What did you find the problem to be? I have this problem also.

[@rancher9625]

My problem turned out to be the screen at the bottom of the supply line that reaches the bottom of the tank.

[@rrf5336]

I replaced the fuel pump. I am getting a dribble on the return line. Is this correct? Should It be a stronger flow???

[@rancher9625]

The return line represents excess that is not used by the injectors. I have not tested the flow rate on my return, but it makes sense that it is a very low rate.

Very useful

Glad was able to help.
