Coast Guard approved fuel line - help

I went to the boat shop to buy some fuel line for my primer bulb. They said the line you have to use is "coast guard" approved therefore it is different than regular fuel line used for automotive. They had two lines, one for inboard motors and then the other they said is required for my primer bulb. It cost $8.99 per foot. I could not use the type of setup for pre-crimped primer bulb/hose setups because it did not work for my setup from take to motor and since I had all the fittings, I just wanted to buy the hose and set it up the way my boat is designed. They just happen to mention that they have had problems with the Atwood line in their primer bulb sets deteriorating after one summer and getting in carburetors. If you are familiar, the line is silver in color. I dont know if that is the case, but he said the line that he would sell me would last for ever.

So the question is , is there different hose lines that are allowed to be used and does anyone know where to get a better price? He gave me a deal, $7.99 - it must of been the look on my face when he said $8.99. I may need some more line and in case I do , I would like to know what types can be used for tank/outboard motor line and where to get a good price.

thanks,
Mike
 
Update from post above:
The hose above is SAE J30RP. In addition to that I found SAE J1527 Type A1, which seems to be marine/cost guard approved.

Again, if anyone knows more of all the types that can be used, please let me know.
 
Careful what you buy there is a fuel pipe that is a sort of silver/grey colour it goes rock hard over the years and loses its flex .SAE 3OR7 is recommended

Thanks for the information. I will take a look at it.
Does anyone know the difference between these coast guard approved fuel lines and automotive fuel lines?

Was it $8.99 / meter by chance ?

The line is marked with a marine/Coast Guard approval on it. It has UV protection and the black rubber line is much thicker and stiffer than automotive. It will resist collapsing when bent as compared to the auto stuff. If you you don't need much, pay the $7.99, otherwise shop on line.
 
The S.A.E. J 1527 was written for two "grades" of marine fuel hose.
Type A and type B.

Each type has additional designators of, for example, Type A-1 and type A-2. The 1 designation is for fuel FEED while the 2 designator is reserved for fuel FILL.

As with all SAE specifications, it gets deep. But, for purposes of discussion here, the type A is considered as required for enclosed engine rooms while the type B-1and B-2 is approved for non enclosed engine spaces.

The S.A.E J 1527 standard has been in force since 2008. While the ISO standard 7840 for small craft fuel conveyance hose was written in 2004 and revised in 2013.

I guess, to answer the question "what should I buy"....you could probably get away with hardware store bulk hose to feed your Honda. I'm pretty sure many do. The Coasties aren't gonna board you and start reading fuel line stampings.

But, if you're concerned with safety, fire prevention, reliability and longevity of your stuff, the J 1527 B-1 is what you're looking for to "feed the beast".
