Easy to work with.
just what I ordered, a length of 303 hose
Areoquip 303 hose does the job in my cherokee.
This is the ticket for replacing fuel lines in early, six cylinder Cessnas. I tape where Iâll be cutting it with a couple layers of tightly wrapped masking tape, then cut it with a fine toothed, bi-metal hacksaw. I then peel off the tape and trim back the outer cotton wrap and steel braiding about 1/8â and itâs ready to be screwed into the fitting: counter-clockwise (lefty-tighty). use plenty of oil on the inner fitting before you thread that inside the hose: clockwise (righty tighty). Use a mandrel! If youâre too broke to buy a new one, watch eBay for a used one, or borrow one.
Item was just as described and hose build up was a snap with the associated fittings.
Great hose. Much easier to assemble than stratoflex. No fire sleeve required. If your old hoses are stiff replace them.
Wrong hose
This stuff lasts forever, but if the cloth braid tears and the underlying metal braid rusts, then the hose could eventually fail. Spruce always sends a piece longer than you ordered and thats good because the device they use to cut the hose makes it impossible to put the ferrule on. You need to make a very clean cut to be able to install the ferrules. I use a Dremel diamond blade cut off wheel.
Great project part for student projects.
Q&A
Yes, the factory gives an 8 year shelf life on 303 hose.
No, Aeroquip 303 hose requires 491 Aeroquip fittings.
Eaton recommends you replace the 303 hose after 5 years of service.
Yes, it is priced and sold by the foot.
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.
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.
This hose is priced and sold by the foot. When you enter quantity, you are entering the number of feet you would like to order.
