I understand there are probably a few options these days for a replacement such a plain rubber, etc but I would like to keep it somewhat original looking if possible. 

Would the PTFE like in this link be the correct stuff?

Original hose is SAE 100R5 and should be common to find.

PTFE hose is going to be more expensive for little gain.

 As has been mentioned, those are "reuseable" fittings and can be removed and transferred to the new hose if compatible with fittings for SAE 100R5. 

[Geoff Weeks]

PTFE hose is used on trucks in some areas where its high heat tolerance is needed.

Turbo oil supply and drain line

Oil cooler lines

air compressor outlet line.

 The line is more expensive and the fittings are different for SAE100-14 PTFE line. 

 It also is harder to work with. 

[mowerman]

Dealer does not carry those you have to have them made. I already went through that couple of months ago with mine I warmed up going to a hydraulic line  shop. They had everything. And those look like the crimp style good luck.. bob

[mowerman]

Or actually, the first photo looks like crimp the rest of them are reusable..bob

[seyser]

Good information!

I will probably stick with the SAE 100R5

Are those original ends pushed on just like a normal barb? I read somewhere that they could be kind of screwed on reverse threads but that might have been something else.

[mowerman]

Yes, that’s what they look like the screw on type except for the first photo hydraulic shop will have everything if you wish to change them. All good luck.

[mowerman]

I paid 75 bucks for three lines with all brand new ends

Anything with a hex on the part that goes over the hose is almost for sure a reuseable, both his look to have a hex.

 Crimp will be a round barrel with crimping marks.

 To remove a re useable, thread onto a fitting or plug and tighten hard, then un-screw the center and plug/fitting from the hose as a unit. It has fine right hand threads. This will leave the lower portion on the hose, that "un threads" from the outside of the hose, it is left hand threaded 

[Geoff Weeks]

One word of caution on fittings. AN and SAE are two different things when it comes to fittings.

 SAE is 45 deg flare and AN or JIC is 37 deg flare.

 In most cases the thread is the same, and while not recommended, nor proper you can fit a JIC fitting on a SAE flare.

-6 and -20 this is not true, the fitting is a different size for SAE vs JIC.

There may be other dash number that this is the case.

 I bring this up because it is something to watch for when making up hoses. 

Cummins used SAE fittings on the turbo oil supply hose, and you either had to source the less common SAE fitting for PTFE hose, or change the fittings to JIC. 

 JIC and AN use the same thread form and flare angle, IIRC the only difference is the lead in the flare/thread is longer on one than the other. 

when in doubt, remove the mating fitting and take it with you when getting replacement hose ends to mate to it.

Any idea what size this hose would be?

[Geoff Weeks]

Hose size is generally marked on the fitting, like -10 for -10 hose or -8 for -8  hose.

 -8 would be my guess, but no point in guessing look at the fitting and be sure.

[seyser]

It looks like AN uses the -8, -10, etc sizes?

It was mentioned that this is SAE so would that be the more common 3/8, 5/16, etc measurements?

Edited August 22 by seyser

[Geoff Weeks]

SAE 100r-5 hose is sized by dash number.

Again, look on the fitted of the hose you want to replace for the dash number size.

here is an example of the -10 hose and fitting, note it is marked with 10 on the fitting, even though it is SAE flare.

 

[seyser]

The fitting shows DOT 1210

 

[seyser]

The other end shows either 9 or 6.

[Geoff Weeks]

Take it off, lay it on the bench and look all over the fitting, either that or take the whole hose to your hose shop, The pictures are not clear enough, nor do they show all sides.

 On the fitting I photo'd above, the "10" is on only one of the 6 flats of the hex. It has DOT stamp on it and some other numbers, also.

 If you don't know what you are dealing with, the best solution is to take it to someone that does. I can't do that from this end of the keyboard.

 a -6 would be 11/16" across the flats if I'm not mistaken.

 Someone fitted a pipe thread fitting on one end, which means you will have to thread the hose on to the pipe thread 1st when assembling then thread the flare. Makes it a bit awkward, if there is a flare at both ends, it doesn't matter which end you assemble 1st.

 

[seyser]

I'll have to pull it off this weekend and take a closer look. I was just hoping to confirm what I have beforehand and maybe get hose and possibly fittings on order. 

I managed to finish changing fluid in rear axles last night. Its getting closer to being ready for work.

My fuel line from the lift pump to the filter is leaking. Is this something still available from the dealer or do people just have them made? Would these be considered AN fittings? Iv browsed the net a bit and see kits to make these style. Are these ends crimped or just pushed on?

That's a steel braid line, very common. I get mine from hosewarehouse.com , they sell by the foot and fittings too. A good choice is Aeroquip FC350; the number after the dash is ID in sixteenths of an inch (-8 is 1/2", etc.). You can go to youtube for videos on how to assemble (outer sleeve is LH thread, hose ends need to be cleaned up).

[mrsmackpaul]

Exactly what was said above,  reusable fittings

Apparently the correct type of hose is needed as some rubber can't handle diesel

Parker 266-8 (black braid) or 206-8 (blue braid) looks like a good option. Its original purpose is air brake hose but it's declared also as for fuel, oil, power steering and even air conditioning lines. So must be resistant to very high pressures and aggressive fluids. And if you install it with reusable fittings (as was recommended and described above) you will achieve the original look regarding to your truck (and mine too)

[seyser]

My driver seat bottom was in poor shape so I removed it a couple weeks ago. I went ahead and pulled all the staples holding the cover onto the wood and inspected the foam, It was still in pretty good shape so that was good for reuse. I took everything including some original tan vinyl to the local upholstery shop. I choose some high wear tweed style fabric for the top and kept the original vinyl for the sides. It all turned out nice and should last many years.

Looks better than any farm truck seat I've seen lol. Like the corduroy look 

[seyser]

Thank you! Yea I kind of wanted it to appear somewhat original. I was going to use a lighter color that would match the vinyl but figured the slightly darker color would show dirt less. Plus it matches the brown interior cab color.

Next interior project will be a new OEM floormat as mine is wore through on the driver side. That will probably be an after harvest project.

[mowerman]

stock Matt’s are available  they are pretty expensive most of us just go through Google search and find some  floor matting  that you like and cut your own pieces. The choice is yours good luck nice thing about changing the floor everything is rubber and it smells like a brand new truck when you get done ha ha… bob
