newbie help diesel line

[rider10099]

The line that runs from the fuel filter to the engine is leaking. When I try and remove it the whole hose wants to turn rather that the nut letting me release the hose. So I have a couple of questions.
1. How do I remove the hose?
2. Where do I go to get a replacement (my dealer is a couple of hours away but may auto parts stores and a farm store close by.
3. Once I replace it - is there anything I need to do before starting up?
I have recived great information from the forum and thanks to all of you who post great information.
But "Big Red" and I have a full day planned tomorrow - but not dripping fuel the way he is.
Cheers
John

Maybe one end doesn't swivel, but other does? If you're gonna replace hose, just cut it. Bleed air from lines all the way to fuel pump and happy tractoring.

Is this a metal line or rubber? If metal, where is it leaking? On a metal line there is usually a fitting which will require 2 wrenches to remove, one to go on the nut on the line and one to hole the fitting still. Also, if it is a metal line and leaking at the fitting, you might be able to just tighten it up to stop the leak. Once again this would require 2 wrenches.
With a bit more info, we can be a lot more helpful.
Good luck.

Just so that readers will know without having to go to the profile, it's a Jinma 204 tractor.
Now, I'm not familiar with that tractor's setup, but I agree with checking it out completely first, and then cutting off the hose to then remove the nut.
If you can get it off without much problem, just take it with you to a NAPA auto parts or similar to see if they can match it up for you or call the dealer and have him mail the part to you.

Should have given more information it is a rubber hose, with a banjo bolt (I think that is what is called on either end. Tried tightening the connections and that didn't stop the problem. The hose feels tired to me for lack of a better word.
And as posted before a Jinma 204.

Who spend most of the day installing gates big enough to get the tractor through so I could mow.

Use a pair of channel lock pliers to hold the banjo from turning while you loosen the bolts. Be gentle, not a lot of jaw force will be needed to hold the banjo still. You can put a rag over the jaws to protect the fitting too.

As noted before, take the entire line to a Napa auto parts store and have a new line made on the spot.

After replacing the line, you need to bleed the air out of the line. Let the downstream fitting (the engine end) leak a bit until bubbles stop appearing. Then tighten the nut. If you can't put a container under the fitting, use ample rags to absorb the fuel that will leak during this. Don't be timid here, waste some fuel to make sure the air is out of the line.

Afer bleeding the air out of the line, start the engine and quickly move the throttle to let it run at a fast idle. The engine will stumble as some air passes through the fuel injection system. The faster idle will help it coast through the no-fuel stages.

Is it leaking at fitting? If so a new seal washer is all that's probably needed, so don't cut that hose! You may just have a burr between banjo and nut from overtightening. Good luck.
