I was looking for some 3/8" hose for my 850. Went and bought some NAPA brand
oil transmission cooler hose. Got home and it is awful loose on the pipes on the oil
filter.
Took a look at the archives and found this:

Transmission oil cooler line from NAPA store sold by the foot. Herringbone and all.



Is it just me that got a loose fit? Usually it takes a bit of fuel to lube up the hose
and forget ever getting it off intact.
Advise on sourcing lines please!
Herringbone history now I guess. :-(
 
Noting is as good and tough lasting as the real deal so start calling world wide vendors or hope someone here has spares or check out Moss Motors.
 
you could put a couple of hose clamps in place and ride around, probably be fine

you will know if it is going to leak quite soon.....
 
Yep just jubulee clip loose fit hoses fluid tight like any good shade tree worth the ticks and bird droppings and ride while shopping for the real deal. The nice used hoses tend to take a set in their shape to help ease routing.
 
Well looks like scylla and charybdis time on this, eh? 145USD for the real deal but Im not going to
live long enough to get value for money. The idea of "you'll find out soon enough" won't do for
a new motor. Most likely to go when hot and at speed . Not comforting.
Fuel line looks good but it is 50 psi @ 72 degrees another iffy proposition.
What the heck are most riders using?
 
I used some 3/8 fuel proof at ace hardware, but I notice it's already cracking at the ends. The stuff I got with the RGM oil filter kit seems to be holding up. Only 3 years now. You could buy the RGM kit for around $50 and get a couple feet of their hose, what ever it is and get a spare filter. The 3/8 I got from ace fits nicely on the metal tubes from the crank, but not tight after I took off the barbs.
 
Had a look at the Trident webpage and funny as recommendations run from fuel line hose to Parker
hose (McMasters stocks) , to Gates 27005 .
I think you are correct that all will do but some will fade sooner than others. In fact, NAPA transmission
hose apparently weeps after a few years.

Ill put down my nickel and makes my choice.
Thanks to all.
 
I just replaced the hoses on my combat with AN-6 (3/8") oil cooler hose from Summit racing. It was $30 for 6 feet which was more than enough for all three hoses, and it even has the herringbone weave cover. It was looser on the fittings than the old hose and when I measured the id with a caliper it was at about .380" the fittings at the engine were about .360". I used all new hose clamps and touqued them down. No leaks. Well except fron my cracked oil tank.... That was another project.
 
I don't know how loose you consider loose but yes you do need hose clamps (as original). It has held up fine.
 
The hose from Napa Auto has a slight pattern to it. It does it's job just fine.
I'm usually going too fast for anyone to see it anyway.
For a concourse bike I'd spring for the good stuff.
 
So long as you use oil cooler or transmission hose you should be fine. Mostly 10mm is available now which is bigger than 3/8" . this is 3/128 " bigger than 3/8". Maybe that's why its loose. Its easier for manufacturers to make 1 hose and put two labels on it than make two hoses. Who no's. I use efi equivalent hose clips on mine. These don't have worm slits in them that the hose can protrude through when tightened.

Why do you think that it is at 50psi?
Oil in feed pipe is being sucked, and with only a very slight restriction because of the metal gauze oil tank filter.
Oil in return pipe is being pushed back to an open pipe in the tank and through a slightly more restrictive paper element filter.
Surely the only place where you could get to 50psi is within the engine after the oil pump?

Must admit I smiled at the 50 pounds as the pump likely puts that out only when cold. Stories of the
oil seal on the DS blowing out and all. Also the 50 pound limit is when room temp which is much less than
when running at temperature.
Suspect there will be no problem for non racing temperate climate conditions.
But being a belt and suspenders type Ill go for Parker hose with AN clamps.
Agree that herringbone is tops.
 
Note only things excessive oil pressure can hurt [besides power drag] is the oil pump to TS case seal and oil lines to head integrity and maybe oil filter & plumbing, but not crank and case or head seals. If DS crank seal pops out its d/t a bad seal and/or surround, a bad install or need to un-clog breather path, as these are unrelated to engine oiling pressure flows. I find i can stare at nice factory hoses longer than the SS braided stuff so commonly seen as an upgrade, which it could be if shielding needed against road debris.
 
SS seems out of place as that was strictly hot rod stuff not really bike stuff back then. Im sure some track
guys did it or guys who worked for Grumman or Republic with back door access to aeroquip stuff.
Porn for me would be a couple of NOS lengths of herringbone for my bikes.
The 145 asking price is what it is but just a bit over my comfort zone having not won the lottery yet.
 
Point that I was trying to make is that there is hardly any pressure at all in the 'rubber' pipes.
Re herringbone, I reluctantly gave it a miss and used plain pipe because of the cost.

I'm not a purist so don't need the herringbone pattern. I'm using power steering return hose along with the clamps they sell to go with. It's more than up to the pressure, fits snugly, it's just smooth. It's better than the braided stainless with the phony ends that hide a screw clamp that I put on many years ago.
 
Just to note that the Parker hose I got today is marked "10mm". It fits more snugly than the NAPA
transmission hose. Good for 225 psi v the 400 of the NAPA.
I used AN hose clamps the gear type that do not pierce the metal.
