Does anyone know if the copper fuel line from primary filter housing to injector pump that has the rubber fitting into the compression fittings can be replaced. They wont stop leaking!

Also, on the flywheel, I only see DC not TDC with lines that are visible in the inspection hole. How many degrees does each line represent?

That tractor never had copper fuel lines on it, until a PO did some replacing. The marks/lines, should represent individual degrees.--------

thanks for the reply, but that didn't help me out....Im thinking that these are compression fittings that are leaking [sucking air into the injection pump] how do I fix this problem?

Get some steel tubing the right size (3/8 brake line possibly), some new sleeves for the fittings and make some new lines.

thanks Jim, I haven't found if the fuel lines should be flared [single flare / double flare... with or without a farel or o-ring into the compression fittings. thanks Jerry

The parts book shows them as rubber sleeves. The tubing should not need a flare with those. Sometimes just changing that sleeve stops the leak, they compress and harden over time. The tubing may be deformed some where they have been riding. Does yours have the rubber sleeves or some type of metal ferrel? 9846567 is the Case part number for the 3/8 rubber sleeves they show in the fuel lines I think you are asking about.

Jim, these lines have rubber sleeves and the sleeves are very hard and somewhat brittle.. I tried O-rings but that didn't work. I have some metal ferrels, I wonder if I should try that to stop the leak. Also on the fuel tank shut off valve, but when I ordered a new a new valve, it's been replaced to a smaller 1/4" line. That means I would have to replace the fuel line from the tank to the filters and all the hardware. hmm? thanks Jerry

If you use metal ferrules you will need to change the fittings and lines to get the ferrules to seal properly. Have you tried getting the right sleeves from a Case dealer? Dieseltech may have them as well.

It doesn't sound right for the new valve to be 1/4" for a diesel. Did the valve come from a Case dealer? The part catalog shows the valve using the 3/8 rubber sleeves like the other fittings. If it has been discontinued you should be able to find a 3/8 NPT valve and fittings to keep the original size line, that would be my path if it were mine.

Case CNH has all the rubber sleeves for all size lines used.

Also a competent injection pump rebuilder usually has them too.

Thanks Tom, my pump guy has them...but its not advised to keep the leaking copper lines, it's time to replace them with steel lines. Napa, Tractor Supply didn't have the steel lines and all connections perhaps just a new counter person! {LOL} but she didn't have the parts, so I think it's time to go somewhere else..I need them asap so mail order won't work and there isn't a dealer within 50 miles.
thanks Jerry

NAPA SHOULD have the 3/8 inch steel line, similar to brake line. It will need cut and bent to the size you need, re-using the line nuts and rubber compression sleeves on each end.

You might have misunderstood what we are talking about. I'm not surprised TSC didn't have auto brake lines, but most auto parts stores generally have a selection of them in various sizes and lengths; standard and metric. NAPA won't have pre-bent fuel lines for your machine, if you want them pre-bent those would be Case parts. The NAPA site on line lists 3/8" steel brake lines, so any store can get it for you. Here are a couple part numbers for plain steel brake lines from the on line site: BK8131242 is 3/8" x 30" long, BK8131245 is 3/8" x 60" long. These are pre-made lines with inverted flare fittings on them. Use a tubing cutter (get a cutter if you don't have one, don't use a hacksaw) to cut the inverted flares off the line and then slide the inverted flare nuts off the tube. To do a neater job, get a tubing bender for 3/8 tubing when you get the lines. Using that bender and your tubing cutter duplicate the old lines. As Dieseltech said reuse the old fittings and nuts, you should only need new sleeves to go in the old fittings.

I did misunderstand you...I did get the right tube cut and bend the brake line, Im not sure but still can't locate the size of the secondary fuel filter bleeder that is built into the filter housing unit. I haven't found a case dealer website, perhaps someone can provide their site / phone number to avoid future case parts. This case is a 580 Construction King powered by 188 diesel. thanks Jerry

First where are you located, general area? People maybe able to give you better ideas on finding parts with that info.

Do you know where you nearest Case construction equipment dealer is located or is that what you want to know?

Do you have a parts manual? If not do you know about and use the on line parts books? Having part numbers helps with searches.

Is this picture your fuel filter set up and are you looking for item key number 20? If not post a picture of what you have.
