190XT Fuel Line Configuration

I decided to eliminate the fuel lines as being the culprit to the tractor not running. A prior owner decided to run a rubber fuel line from the right-hand sediment bowl into a T fitting right before the engine. I think I have uploaded the image from Agco parts book that shows an original metal line running from right-hand sediment bowl to the left-hand sediment bowl, then onto the engine.

I don't think it matters where the lines intersect but I don't like the use of the rubber line, so my question is should I run a metal fuel line to the existing T fitting or should I remove this and run a metal line to the sediment bowl as original? It is a lot easier to run it to the existing T fitting though rather than doing it as original setup.

Thanks for looking at yours and you understood my question exactly. Thanks for verifying the fuel line configuration. Mine appears to have the original sediment bowls but after inspecting them, I decided to replace them. With the valve screwed all the way out, the opening was still quite small and partially blocked with the stopper that got moved in. I think the last guy had some leaks and he moved the valves nuts in to stop it, but he also restricted the fuel and gunk flow. One of the bowls was completely blocked when I cleaned it because the gunk couldn't drop into the sediment bowl due to the small opening. I have two new bowls with stopper going all the way back and plenty of flow now. So, sediment bowls should work as designed.

Even though I had the original sediment bowls, the dual port fitting on the one bowl is gone. I never thought about the heat from the hydraulics but that rubber line is running right by that stuff. So, while a bit of a pain, I am going to route the lines back to original. Sometimes the small stuff can matter in the long run.

I have drained the tank twice of about 10 gallons of fuel, I replaced the sediment bowls and some of the fuel lines, I also blew out the lines up to the Fuel Filter canister to make sure there was no gunk left. Hopefully the rebuild of the injector pump will fix it. I don't know how to insure that the return fuel line isn't clogged. I suppose I could shoot some air into that last fitting back towards the tank? Would that do any good?

I dont see a problem with blowing air back thru the return line. The bowls are suppose to catch some of the dirt, but the main filter should catch the rest as long as it is changed at the recommended intervals. Lol, such a pain to do and what a mess. But it needs to be done at the recommended intervals to protect the pump. A filter is only good if it has done its job and changed before the pleats become clogged. A steady fuel flow to the pump is key to good performance. I think your wise for following the factory route. The engineers that designed them did so for a reason.

Ac720Man,

I should have probably changed those filters as soon as I bought it, but it ran so good and they looked new, so I didn't. I have changed all of the filters I can find now.

I just bought a 190 XT, had a few bad fuel leaks under the tank, so I have the tank off, it appears that everything is original just like the pic in the above posting, I cleaned the tank out and 2 new sediment bowls, now I am having a real hard time getting the rubber grommet's in the nuts far enough to start the threading them on, there has to be a trick to it. Any help would be greatly appreciated, thanks in advance.

Thanks Dakota Dave, but the problem is I can't get the rubber inside the nut far enough to start the threads, I worked about 3 hours yesterday just on the cross over line with the tank on saw horses. Thanks for the tip on the tape, was always told brass on brass don't need tape.

Thanks injpumpEd, yes I have new rubbers and can't seem to get them in the nut fare enough to show the threads in the nut, and just can't get the nut started. I have the tank sitting on saw horses and was working on the cross over line first, what do I have to do to get the new rubber ferules deeper in to the nut so it will start?

I have an early gas 190. I bought it at an auction. I started it to load onto my gooseneck trailer and it ran almost to the trailer then died. I found that the valve on the sediment bowl was closed so I opened it and was able to get it loaded. I never gave it a thought to close the sediment bowl valve. When I got home I had gasoline on the deck of the trailer. I never could stop it from leaking. I removed the fuel line and found that the rubber seals on the line were shot. I was able to find a NOS line and attempted to remove the old line and install the new line. What a job that turned into. I'm not a small guy and room under that tractor was a challenge for me . I decided to change both sediment bowls at the same time. That move has proven to be a ongoing problem with leaks. The bowls have to be in PERFECT alinement  to get the fuel line connected to avoid cross threading but doing that would mean that the sediment bowls were not tight. I purchased ( twice) new sediment bowls that were advertised and sold as being correct replacements for a 190 gas. Anyway getting that line installed was a long job. I still have leaks. I've now found STUFF in the tank which I'm sure is causing it not to start. I'm going to what I should have none to start with, remove the tank, have cleaned and maybe lined install the sediment bowls and fuel line while it's off and re-install the fuel tank and hope and pray it works. Our Dad always had a saying about things like this " boy's if the engineer that designed such a thing had to work on it or repair it their would be some changes".

Okay, thanks for all the help and tips DougG, injpumpEd and rodnil, I spent all day yesterday working on this and getting all the old rubbers out was a chore, ended up removing the fuel line up to the middle of the tractor, at least I could get both hands on it to remove the old rubbers with a small pic, but was still a time consuming pain, they came out in little pieces, and still had a hard time getting the new ones in fare enough to see threads, even had another fitting to assure they would start when I set the tank back in place, but not ready for that yet, got to go get 1/4" rubbers for the return line. I recently bought a parts tractor from a neighbor for the good injector pump for my 200, my tank had a big dent in it so I swapted tanks and the new tank was the cleaner of the 2, and the 190 and 200 tanks are almost the same as the whole tractors are almost, only some one had removed the sediment bowls on both 200 tank and had different lines, they were much easier to mess with, but not original, the 200 has the square glass fuel filter and almost the same on the water separator just before the filter, some one had removed the water separator on my 200 but the mounts for that were still on the parts tractor, I haven't found the right nuts for that fitting to put it back on, and my 190 has a spin on fuel filter, is that original for the 190, or has some one changed that? And on the 190 they have added a small fuel pump, and I see why, they didn't drain the tank or even look at the sediment bowls, both had that black gunk from todays fuel, inside the tank on top of the sediment bowls was full of it restocking the flow. At the end of hay season last year my 200 would die, I could use the hand primer a bit and would start right back up and run for a while, did that more than a couple times, so talking around I figured the governor in the injector pump was out, so I let it set all winter then when I had to I bought the parts tractor (200) from the neighbor, he said it had a newly rebuilt pump on it, and his hired hand run it for 2 weeks and didn't check the water or oil and burned up the motor. Thanks for all the help guys, maybe today I will get the tank back on and have it running again.

Had you not cleaned it out your new injection pump wouldn't last long. they don't survive on old fuel and gunk.

I believe the spinon fuel filter is original. The spinon filter part number is listed in the parts book. Many of the auto parts suppliers also listed a compatible spinon fuel filter. I have seen quite a few 190XTs in pictures and they seem to all have spinon fuel filters. Glad to know that you got it fixed and are moving onto the next problem. I wish I had all of the gas money I have spent going back and forth getting the right part, as I am sure you do too.
