This time not necessarily a request for advice but rather what I've been dealing. Feel free to pitch in though. This tractor is new to me and always started great till just a week ago then yesterday no start no smoke. There is no primer on this tractor so I disconnected the fuel at the injector pump and had almost no flow. Went to the inlet side of the fuel filter, again almost no flow. Back to the sediment bowls  Screens are clogged. This stuff is gooey and sticky like uncredited gasket sealer. Presumably bio diesel crud. Anyway, got it all cleaned up.  Decided to drain the tank completely as the fuel left in there is cloudy  I poured some gas in the tank to act as a solvent to cut the crud as that appears similar to molasses. I clanped a brush on a stick to scrub some. Obviously I can't get all of it due to the baffle but some is better than none. I now have 10 gallons fresh diesel, clean sediment bowls and new filter. Have good flow out the sediment bowls but not so much from line itself. I did get the tractor to start and run briefly but I think there is still a restriction in the supply line. Ran out of time yesterday and this is an outdoor project with rain today's so will have to wait some. Thanks for looking |

| I haven't used any screens for 40 or more years. It's always the first place that gives problems in the winter time. The fuel filter catches all the dirt. Throw the screens away to eliminate a problem at that point. |

Take the tank to a shop to get completely cleaned out and your problem will be eliminated. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '61 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

My xt sat for 28 years when I got her. Ended up power washing inside tank. Threw away bowl screens. Not an issue since. ------------- Blue Skies and Tail Winds Dana |

| Clean up fuel system as best as you can and treat fresh fuel with bio kleen. Sounds like algae |

I dealt with a bad fuel line, gunk in tank, bad sediment bowls all at the same time so I feel your pain. I have often wondered if the tank cleaners can really get the gunk out with the baffle? I drained my tank multiple times. My needle valves in the sediment bowls got restricted multiple times until I got it all out. I also do want to relate a story about removing the screens. I left the cap off of my fuel tank, mowed 2 acres of weedy, fluffy seeds floating around. A bunch of seeds got into my tank, and clogged up the check valve in the primer pump. It was self inflicted. The primer pump is in front of the fuel filter. Otherwise, I think screen removal is fine. ------------- 80 7010 w/Cab, 67 190XTD Series I w/500 Loader, AC 2000 Plow, AC 4 row Planter, AC 77G Rake, Member Indiana A-C Partners, Member TAC |

To each his own but I leave my screens in as they were designed to help keep dirt out. Cleaned them 8 years ago when I got the XT and haven’t had to touch them since. I never run Bio Diesel, I am not a fan of it. Thankfully there are plenty of stores that sell off road diesel for my tractors. Cleaned your fuel containers and wiping the fuel cap and neck with a clean rag before refueling will keep dirt out of your tank. Realizing this is new to you the only good way of resolving your issue is a really good cleaning of the tank. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

I would unscrew the sediment bowls from the tank and insert about a 2" long roll pin in the middle of the bowls to stick up in the tank - this will prevent a 'sink stopper' effect if a rust flake occurs. The slot in the roll pin will allow the tank to drain . A stand pipe will never let the tank drain and the results are not pretty. With today's fuel and algae, I would vote no on the screens. The main reason is they are so hard to get to at 70 years of age... the fuel filter is not. ------------- When told "it's not the money,it's the principle", remember, it's always the money.. |

| There is nothing more unpleasant that cleaning screens in the wintertime cold while the fuel is dripping off your elbow !!! Throw them away !!! |

| Screens are out. At present, I am not able to get fuel through the injector pump to the injectors. Have loosened 3 lines at the injectors. Nothing so far but now also fighting an intermittent starter solenoid and maintaining battery charge. To think, all I wanted to do was try to isolate a buzzing hydraulic line from the pump tooil cooler |

I typically run a 90/10 mixture of diesel/acetone through a system that is sticky or gummed up from this crap biodiesel we have. Have a spare set of filters with you as the sludge and grime will release with the filters catching it. If really bad, filters will plug, but the fresh fuel and acetone act very well together and don't seem to hurt anything; or at least hasn't for me in many years with diesel engines of several types. You could also use naptha, but the desired results take longer to achieve. Many times transfer pumps and their check valves are the first things to stick precluding fuel flow and this mixture will get them freed back up and working. Same thing with injectors. ------------- A career built on repairing and improving engineering design deficiencies, shortcomings, and failures over 50 years now. |
