| The fuel pump on my 180 gas is getting weak and planning to eliminate the pump and run a line from the tank directly to the carb. I plan on putting an inline fuel filter in as well. Has anyone else tried this? Why would Allis have designed a fuel pump on the 180 when the tank sits above the carb? |

| I did a 185 like that 10 years ago for a farmer uses it in the field |

| Didn't know they made a 185 gasser ?? Anyway, if it will pull a plow in up hills when it is at 1/4 tank, I guess you don't need a fuel pump. Hard to believe the Engineers couldn't have figured that one out because they are always looking for a place to cut costs. |

| Just exactly HOW do you know thew pump is getting "weak" ?? is it leaking,sediment bowl only 1/2 full and VERY foamy?? Got a feeling you have something else going on, JMO, and yes, we run one !! |

| Thanks for the responses. I installed the gravity system and it didn’t correct the fuel flow issue. Pulled the brand new carb off (only 2 hours of run time) and it was full of rust. Cleaned the carb and it runs perfect. I’m going to keep the gravity system for awhile until I can get most of the rust out of the tank. Hopefully the automotive style fuel filter will do a better job than the sediment bowl. |

| If the carb that new is full of rust, so is the bottom of your tank, the 180 fuel pump runs off of the cam gear , I think,, so if any more problems id clean the tank and put an electric in line pump in |

| I’d tank the tank off, but it’s got a cab on it. |

| Gravity will work (on a 190 i know for sure), but its almost like having half a tank all the time. If the level gets too low you lose flow and power. Its pretty cheap and easy to wire and plumb in a little inline electric pump. |

I run my 180 gas gravity flow and an inline filter, works OK just keep it over half full of gas which its better to keep any fuel tank near full all the time to reduce rust and condensation problems.I've found that a sediment bowl doesn't do a very good job of keeping things out of the carb.Even with a sediment bowl its surprising how many fine particles will show up in a clear in line filter.Run in line filters on all my gassers.

| Get one of the small screens that goes in the top of the sediment bowl inlet. It will help keep most of the crud from even entering the sediment bowl. Steiner sells them. |

| The problem with that is, when it gets plugged, then you have to remove the sediment bowl from the tank to clean it. An in-line disposable filter is much easier to service. |

| Our "bowl" is located directly upstream from the fuel pump(actually plumbed into the pump). There is no way in H%^L that a sediment bowl could be attatched to the bottom of the tank(gasser) let alone accessed for cleaning. JMO |

| Well, you've never seen an older One-Eighty diesel, because that's where they were......on the bottom of the tank. |

I have the screens,it'll let particles thru that will foul up the workings of the carb.Like i said its surprising what that in line fuel filter catches and certainly wouldn't want it in the carb.

Get the tank cleaned out and lined if needed and that will solve all of your problems. With a clean tank, clean sediment bowl, clean fuel line and clean carb you will not have any more fuel issues. Good and clean gas is always important too - never use those big gas barrels on the farm - they get tons of condensation in them (and rain water too). I understand getting the tank off a cab tractor will be a bugger, but it is needed in this case. Anything else you do is a band aid that does not eliminate the problem. No need for an inline filter either. None of my tractors have them and I've never had any problems. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

So you can guarantee that all the gasoline you ever buy will never have any foreign matter in it? Gas suppliers in my area aren't that good,I've seen things show up in gas cans that the only way it got there was from the gas.

Of course I cannot guarantee that, no one can! But I can say that fresh gas from the station will be of far better quality than that which has been sitting in a rusty gas barrel on the farm for years. Those things are the #1 source for fuel problems in a tractor. Any debris that gets in your tank will settle in the bottom of the fuel bowl. Just clean it out whenever it needs it. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

Tiny particles can and will go right on into the fuel line to the carb as witnessed by what I see in the clear in line filters.A minute particle can foul up a needle valve or the jet in the carb

I'm with Myron on this. I've used only the sediment bowl my whole life and I have never had a problem, but I've read about a lot of people on here with a dirty tank and inline filter that are having problems.

| I replaced the fuel pump on my 180 several years ago, last year that one took a crap so bought a electric in line pump, installed an inline filter and ended my carb. problems. Tractor has never run better and I have had it for 25 years. I use cans to transport my gas and just last week, added 2 - 5 gal cans and by the time I was done the screen in my funnel was nearly blocked by ice crystals. I added a can of heat to the gas and she runs fine. I gave up using gasohol, just use regular. I use mine mostly in winter to blow snow off our 1/4 mile driveway. Love that tractor. |

I have no doubt that a diesel bowl is "there", I imagine that's why there a 2 part #'s in the parts book?? There is hardly room to access the shut-off on our gasser,let alone jam a sediment bowl under there. And "NO", I have never seen an older 180 diesel.
