Hi-
lately my engine RPMs are not able to stay constant, in the late fall I was running around 2500 RPMs or so and after 5 minutes or so it would start to drop especially under load (grading) then i would stop, let it drop to under 900rpm and eventually come back up to 1200 or so then i can raise it up but only for a limited time. Very strange.
Last week, this happened again but now at idle in the 1000 range. Almost like there is no fuel in the line and then it comes back....
I use fuel conditioner, Also use my tractor once a month during the winter to move firewood, but that has never had a negative effect in years past.
Any tips n tricks would be greatly appreciated.
Thanks,
dave

Is the Tractor stored indoors or outside?

Do you keep the tank full when stored for long periods?

Asking because it sounds like you have might have gunk or sediment in the fuel tank, so that as the rate of flow goes up with higher RPM demands the clogging increases as the fuel draw causes gunk to block fuel from leaving tank.

Best of luck ....

Hi, thanks for your reply.
Answers to your questions:
I keep it in a shed, so its dry and out of the direct weather, but not insulated or heated.
I do try to keep it always over 3/4 full but not every time, usually during the warmer months when I use my tractor weekly.

Yeah another friend with many tractors said there may be sediment or algae in the tank / lines. it's been kinda cold so i have been reluctant to work in it lately.

I don't need to use to for at least 3 weeks or so... hopefully there will be a 40 degree day when i can change the filter and bleed the lines.

Any tips for draining the tank? I will guess: get a 3-4 foot line and connect to just after the filter valve and run that into an empty diesel can.
I've not drained the tank, so any info is greatly appreciated.

Thanks,
dave

Here is a guide to cleaning a tank on a Kubota that may help:


HOW TO CLEAN YOUR TRACTOR’S DIESEL FUEL TANK
How to Properly Remove Water and Clean Your Tractor’s Diesel Fuel Tank.

If your diesel powered Kubota tractor or construction equipment sits idle a few months without operating, water, sedatives or other contaminants could appear in the fuel tank and clog up the fuel lines. You’ll most likely discover this situation shortly after you start up your Kubota. Not too long after you fire up the engine, it will most like cut off – as if it’s out of fuel.

When this happens, it’s important to drain the fuel and clean the tank and fuel lines on your tractor. Below are the steps to properly drain and clean your diesel fuel tank.

To tackle this project, you’ll need the following items:

Wrench set
Container to catch the diesel fuel
Fluid extraction pump with a flexible hose
Air compressor with high-pressure nozzle
Your Kubota owners manual
Ultra Low Sulfur Diesel fuel tank cleaner, such as Power Service Clear-Diesel Fuel & Tank Cleaner
Replacement fuel filter(s)
Step 1: Remove the fuel cap.
Step 2: Place the fuel catching container under the tank.
Step 3: Unscrew the fuel line nut or hose on the base of the fuel tank.
Step 4: Once the tank stops draining, use the extraction pump to remove any fuel and sediment settled at the base of the tank. It may be necessary to blow out debris with the air compressor.
Step 5: Remove your fuel line just before your fuel rail or injection pump. Insert the air compressor nozzle in the hose and blow air back toward the tank to remove any debris in the fuel lines. After blowing out the lines, replace and secure them.
Step 6: Screw the diesel fuel line nut or hose back onto the base of the diesel fuel tank.
Step 7: If equipped, drain water separator and replace fuel filters.
Step 8: Fill up the tank with fresh diesel fuel.
Step 9: Pour the correct amount of diesel fuel tank cleaner into the tank.
Step 10: Replace the fuel cap and fire up your machine.
Step 11: Bleed your fuel system. On later model Kubota tractors, turn your key on and allow the electric fuel pump to flow fuel up to the filters. Crank the engine over until it self bleeds and starts.

On models with injection pumps, there is a bleeder screw where the fuel line meets the injection pump. Open the bleeder screw to purge air and crank the engine until it starts. When the engine starts, close the bleeder screw. Please consult your owner’s manual to identify which system you have and for further details.

With those steps completed, your tractor diesel fuel tank should be clean for trouble-free operation of your tractor or other diesel-powered equipment.

Before you get too excited tearing into a big messy job like cleaning out the tank, siphoning or run down the tank and using an inspection camera or mirror and flashlight will show if there's debris.

If your machine runs rubber fuel lines I would seriously look at changing them out for good quality new stuff.

I've seen lots of offshore fuel line going bad in the last few years. What happens is that the inner wall of the tube goes soft and under the slightest vacuum the line collapses and shuts off the flow of fuel to the engine.


Best of luck. ....

Thanks much!
I'm going to change the fuel filter today, it's finally warm enough to work on it.
I was thinking of replacing the fuel lines as well, certainly if the fuel filter change doesn't solve the issue.

I'll guess I can just buy a roll of line and cut to length?

Thoughts/concerns? ....

Fuel filters certainly do clog up, but they rarely clean themselves. It is possible that you got some bad fuel and have ice / wax / gelled fuel issues, but normally those go away or at least get a lot better as the machine warms up and things melt.

Changing fuel lines is a (fairly) cheap and easy place to start. Just measure up how much you need of what size and buy that much from your local parts store. Unless you do a lot of engine work leftover line will just age and harden until you need it and it's gone bad. LOL.


Best of luck. ....

Yeah just buy what you need, depending where you buy could be a precut length, but as Murf said the stuff dries out and you rarely need it.

How are you making out with this has the warm weather helped any? ....

Hi all- Well... no updates yet. Its been cold and i'm still snowboarding these days. This week we will be in the 60's so maybe I will get out there and change the fuel filter and bleed the line and also check to see how strong the fuel comes out of the line at the Block! I will let you all know :)
thanks again- ....

Hello everyone!
Thank you again for all your information.
I changed the fuel filter and that solved the issue. It was so dirty and there was sediment in the bottom of the filter cup. But that's no surprise since I didn't change it last year... I will never make that mistake again.

I will keep the info everyone gave me for future use in case something goes awry.

So nice to be able to use my machine again :)

Cheers,
Dave ....
