Great product, requires some muscle to get the hose ends to start. My advice, buy the mandrels for the hose size you are using. Without the mandrel you will most likely create a flapper valve on the inner wall of the hose and cause oil or fuel starvation. Use lots of oil in the hose and on the fittings during assembly. The 303 hose will most likely outlive the installer, its a solid and reliable product.

Q: Does this hose have a shelf-life?

Yes, the factory gives an 8 year shelf life on 303 hose.

Q: Can you use regular AN fittings on this Aeroquip 303 hose?

No, Aeroquip 303 hose requires 491 Aeroquip fittings.

Q: If this hose is used for fuel line, and is installed within its shelf life, is its installed service life limited to 8 years before needing replacement?

Eaton recommends you replace the 303 hose after 5 years of service.

Q: Is the Aeroquip 303 hose priced and sold by the foot?

Yes, it is priced and sold by the foot.

Q: Does the Aeroquip 303 hose contain any metal or wire? Is it conductive?

The tech data sheet shows the Aeroquip 303 hose has a carbon steel wire braid reinforcement. It does not give any information regarding how conductive it may be.

Q: Do you still need to use fire sleeve for this Aeroquip 303 hose?

It is up to you if you would like to use a firesleeve on this hose or not. It will all depend on your application if you were to need a firesleeve. If you were to get a fire sleeve for hose 303-4 for example, you will need to get P/N# 05-01843.

It is recommended to use Stratoflex fittings with Stratoflex hose, and Aeroquip fittings with Aeroquip hose. The Aeroquip 303 and Stratoflex 111 are equivalent to each other, and some have used parts interchangeably, but we have no documentation as to how well they will work.
