Today coming home from a great day of cruising I blew a transmission cooler line. What a mess. Oil everywhere. I mistakenly used a piece of 5/16th fuel hose on the transmission cooler. Well not really mistakenly. I thought that if it was rated for fuel it would be oil resistant. Wrong! I am sharing this in the hope that my lesson will prevent this from happening to someone else. Here is a very nice article on the subject.

So what is the best way to remove oily residue from virtually every component on the right side of the car from the front to the rear?

Wow. I've used fuel line hose for that before with no problems.

Live and learn, huh?

Thanks.

Bummer dude, The self serve get out and spray it yourself carwashes here, have a mode for engine degreaser. You might try that if you have them in your area.

That does sound like mess i'm not sure why a gas hose would fail with oil...maybe there is a rubber expert here

And thinking more hydraulic hose is rated for pressure and temp. But your trans shouldnt get that extreme...interesting

The nastiest is the rubber lines rated for brake fluid.

Thanks for posting your experience. Something else to worry about ...

A friend had the same issue with his miniature Kenworth/pick-up. Blew the fuel hose splice on his tranny on a short cruise around town. Regular (old type) fuel hose is for low pressure application and the tranny cooler line pressure is much higher, so he blew the fuel hose.

Surely that was outlined in the attached article.
Different lubricating oils have different chemical properties, and fuels do too. So the manufacturers make hoses to suit the applications they will be used for.
If a spokesman for Gates or Dayco says they can't make a "One size fits all" hose, I'm inclined to believe them.

yup.ever see a car with a blown oil cooler in the radiator.all the coolant hoses will swell,turn to mush and have a sticky feel to em.as for the hoses they are usually clearly marked fuel,trans etc.

I use hyd hose for my coolant lines from the transmission to the radiator routed over the wheel well. Been on there a few years now with no issues.

The article is interesting, thanks for posting. Most of this I already knew. What I didn't know was about the in tank pump hose. I've never done an in tank pump, but that's interesting and a bit crazy they can't make hose that works in + out!

Ditto.
Also, transmission fluid has detergents that probably shorten the life of hose that's not for that specific application.

Here is a pic of the blown hose. There is a couple mm slit. I believe the failure is pressure rated. The hose is rated J302.7.

Here is the correct hose.

I bought this through Car Quest.
I guess all 5/16th rubber hose is not created equal. I hope this info will spare someone else some frustration.

Time to take short lengths of the various hoses in my "hose" bin and treat them to a summer soak in today's fuel.

IIRC "Not For Fuel Injection" hose is rated appx 40psi
