Mystery part number

[yankeeleeroy]

Help! I have a Deere 2640 with a 4039 motor in it. The steel fuel line between the lift pump and fuel filter has a crack and needs to be replaced. None of the parts diagrams show the same fuel line configuration, and our local Deere shop can’t figure it out either. Any thoughts? It’s the line in the background of the picture that runs alongside the block…. I’m just trying to figure out the part number

Item 15 maybe?

That would be my guess also, betting the fitting on the side of the filter was changed and the line bent to fit.

On mine, The end that threads into the fuel filter housing is straight with no bends, so I don’t think so. Thanks

What difference does that make? If it goes from the pump to the filter base, that's the part you want. Or you can always cut out the damaged section, slip a section of 5/16 hose over both ends with #4 hose clamps. That's probably what I would do.

Where's the crack? If it's far enough from a fitting, just braze it. That job would have been over and done with a half hour after it happened.

The crack is right behind the flare on the filter side

Have you owned it since it was new and can verify for us that engine has not been replaced or the line worked on?

My thought is that some time in its life your tractor has had the engine replaced. The 2640 used a naturally aspirated 4276 engine, not a 4039. that means the line may not be the same as the 2640 parts book shows.

That the line to a hydraulic shop and have them make a hose to replace it. single wire will be fine, even Pushlock type will be fine, and easier to deal with than the solid steel line.

Definitely not the original motor, had the Deere shop focus on the serial number of the motor instead of the model of the tractor. Sent them pictures of it and no luck

The 4039 is used in many industrial applications, not just tractors. They could search for a long time and not find a line like that. That line may very well have been modified. It is possible the 4039 had a different fuel filter before and who ever changed the engine modified the line to fit the original filter of the 4276 (minus the 90-degree fitting), including possibly cutting it down and making a new flare on the filter end.

If you find one, that tube is likely going to be in $50 range. If you want to take a chance get the 90 fitting and the tube for a 4276, it may well fit as those engines will interchange a number of parts. I get a hose made; it goes on easier and life is simpler. JMHO.

Would there be any issues with a hose directly beside the motor block? One person warned me that the heat from the motor could cause lots of issues with a hose so it needs to be a steel line. ???

I would think you could route a hose so that there is an air gap around it. Even split a larger hose and make a cover for it. Where there is a will, there is a way (and sometimes relatives)!

Many diesels are running in the world with hoses not steel tubes. Oil rated hoses can carry oil at temperatures higher than that line on the outside of the block will see. An operating hydraulic system oil can approach 300 degrees on a hot day. You are dealing with diesel not gasoline and it is lower on the block far away from the manifolds. You can get braided stainless steel outer casing hose if you want. I would just use Push loc or a single wire hydraulic hose.

Thanks for all the insight!
