On youtube there is a guy fixing oil cooler lines, I hope this link gets you close. Sorry my browser won't let me copy and paste live links but this should help you find it.
This video is giving me some Ideas. What do you think?

 

The idea that I had when I first watched this video is, If I could replace the weak rubber hose with high pressure hydraulic hose that sometimes lasts 40 + years in all sorts of weather conditions one would ever have to worry about them again and wouldn't be afraid to go on long trips as I am because of my nearly 19 yr old hoses. There is a local hydraulic hose shop near me that I'm going to check with on the subject.

Great idea, keep us posted....

 

I wonder if fuel injection clamps would be a better choice. Looks like a reasonable fix though!

 

No use in buying new factory hoses if you can't trust them. I'm not familiar with fuel injection clamps but it would be a cheap fix if one could just buy a few feet of hydraulic hose and some good clamps. I suppose the hightest pressure wouldn't of 60 to 70 lbs. probably less.

 

Just doing a quick look, lots of pumps say they are rated at around 1200psi, so i would think the high pressure side gets pretty high lol. This is a fuel injection type hose clamp

 

That would be a better clamp for even pressure around hose and strength. it also has beveled edges to prevent cutting hose.

 

I've been through a few oil line issues lately. A better fix is always welcome. I have a complete set of lines since I replaced them all, one new piece and 3 used. Not a good idea, don't ask how I know. I'm going to take the set to a braided line shop near me and have some made from the fittings. TM

 

^^ Sounds like a good idea, keep us posted on how it turns out....

 

Repaired my oil cooler lines with new hose back in may 2020. My thread and details are included.

I wrote about this issue several years ago here on the Forum re: one of my XJ-Rs with the same oil cooler lines. One of mine blew out and I found a hydraulics shop that cut me some hi-pressure hose to replace those sections. Just used good quality hose clamps to secure them after aligning the fittings to the cooler and engine block. I would also suggest NOT using the oem o-rings into the block, but find some very slightly oversized oil-compatible o-rings because my oem's leaked immediately. Never had even the tiniest leak on either hose or the fittings in the years since. Total cost about $40 !

 

I one could form the tinniest of bulg at tip of tubing and with a good clamp there would be no way the hose would ever blow off.

I've been researching hydraulic hose on the net. H5HT-12 5/8" SAE 100R5 High temp -40 F-300 F 1500 psi max working pressure 6000 min burst pressure. 1.08 OD 6.5 bend radius looks promising.

Will you re-use your existing fittings or will you source new ones?

 

I will reuse the old ones. It will be this winter if I decide to go ahead with it.

 

Keep us posted once you tackle this project. Thanks....

 

I will.

Here is an interesting clamp that might be good for this project.
Hope the link works

That one in particular would be massive compared to whats needed lol. In function, pretty similar to the one i shared
