Fuel Hose SAE J30 R10 Marking?
I bought some fuel hose online, advertised as J30 R10, it has arrived, but, has no markings on it, all the other fuel hose I've bought has been
printed along its length J30 R6 etc.
I'm rebuilding my fuel system, and went for the top notch stuff, but I'm wary now with it not being printed, I've mailed the
supplier, but in the meantime does anyone know of R10 is generally marked?
Cheers.
Pete.

I'd send it back, even if the supplier says it is, how do they know being as it has no markings on it?

Try Here
Info on all standards
As said above if its not printed on the hose send it back
If its going to be tested ie IVA/SVA the tester will need proof.
read page 35 Item 7

So am I, but can only be used with screw on fitting. Won't work with barbed hose connections, which all of mine are...

Cheers guys, I've done a bit more reading and it seems,
J30R10 is for use when submerged in a fuel tank for example, but is not suitable in under bonnet areas, heat oil mist, etc.
J30R9 is for use under bonnet, but not for use submerged in fuel.
The outer coatings on the two are different, for the differing environments, and either will fail if used in the wrong place....
So what I really needed was J30 R9!!!!

4.5 Fuel Injection Hose Medium-Pressure Coupled and Uncoupled Synthetic Rubber Tube and Cover (SAE 30R9) Hose primarily intended to meet the demands
of fuel injection systems. These would include, for example, electronic fuel metering (EFM), electronic fuel injection (EFI), throttle body injection
(TBI), and the like. Other areas of utility are those applications requiring fuel permeation resistance exceeding 30R8 and ones which require fuel
resistance greater than that obtainable with 30R6, 7, and 8. Exposure of this hose to gasoline or diesel fuel that contains high levels, greater than
5% by volume, of oxygenates, i.e., ethanol, methanol, or MTBE may result in significantly higher permeation rates than realized with ASTM Fuel C. This
hose may be supplied in either a coupled or uncoupled form, and is useful in the transportation of gasoline, ethanol extended gasoline, diesel fuel,
lubrication oil, or the vapor present in either the fuel system or the crankcase of internal combustion engines in mobile, stationary, and marine
applications.
This hose has a maximum working pressure of 0.69 MPa (100 psi) up to and including 12.70 mm (1/2 in) ID.
So, I've got some marine fuel hose, with a working pressure of 10bar, which exceeds all the above, and is fire retardant. Shouldn't be a
problem then?
Might be worth considering Pete. I got mine from the local marina. Very cheap, and has all the codes printed along it if you want some? 8, 10, and
12mm
Can't get the pic to upload, but printed on it is nautilus fuel master-marine fuel-iso7840 a1-wp 10 bar then some tape covered the next bit, but
appears to just be the size, it starts 1/2" *tape* T 35503
