Can you use fuel hose for transmission cooling lines?

Are compression fittings good for fuel lines?

Double flare tubing compression fittings are safe to use on fuel and hydraulic lines. Compression fittings are the perfect choice for high pressure applications. In combination with a high pressure tubing material like steel, large compression fittings can often be used at pressures in excess of 10,000 psig.

Can you use compression fittings on steel tubing?

Can a rubber line be used for trans fluid?

Trans fluid & regular rubber fuel line aren’t compatible, as it will swell it & leak. If I have to use any hose on the transmission line, I usually flare the steel line before I slip on the rubber hose, it helps to keep the hose from blowing off.
