fuel line requirment for MCs

[panchop]

Do i need steel braided lines or is any quality rubber line OK. Steel braided dosen't bend so easy ion tight quarters.

Greg, the only requirement is for any " unvalved" sections of fuel line, they must be fireproof ( braided) or have Firesleeve over the top.IIRC as I do not have a rulebook at this station,working OT.

[Dean Los Angeles]

"Unvalved" would be any fuel lines that cross over and don't have a shut off. Otherwise, plastic fuel line is not allowed "except certified clear fuel lines, clearly marked on the fuel line by the manufacturer for fuel application." Metal screw clamps are required. 7.B.25 Fuel Systems

I think you'll find that braided fuel line is unacceptable.  You'll probably find you will have to use firesleeve. 

[panchop]

OK so unvalved would mean all the stuff that runs between my pumps , regulator, carbs etc. plastic line? to me that isn't the same as black rubber fuel line. is that correct. when i Google aeroquip it seems to be a brand name not necessarily  a type of cover. is Aeroquip the only one allowed. So if I run my black rubber 3/8 fuel line. cover it in Aeroquip . fasten it to the various barbs with everyday autozone screw clamps. i am good to go?

I have run Gas class recently.......the inspector told me
he wanted the firesleeve on portions of my system,
a couple  places where I was between 1-2 ft distance,
and I dont have ANY unvalved sections.....so its at the
discretion of tech..........not only on unvalved.........

it wasnt a new system....same one I had run for
4 years.........

ok by me though........

Unruly discretion is it's own reward.

Oh great, MORE confusion on the rules interpretation. At Speedweek 06, the inspector told me that the lines must be stainless braided or fire sleeved. So I replaced all lines with stainless braid and have passed two more inspections with that. So obviously braided is OK.

so to rehash. my rubber fuel lines with screw type clamps on the barbs. i bought something called  thermocool which seems to be the same thing as the aeroquip stuff. Now those pieces DON"T need an additional screw clamp onto the fuel line correct?

[joea]

better ask Tech Committee........

[ol38y]

Stainless braided is not fireproof, but what do I know. 

[isiahstites]

So what is allowed and what is not?? I am confused?? I am running the gas class with a single line from the petcock to the carb...........

Should need nothing. I have had braided line on all my lines for several years and it passed. Before that I used Firesleeve brand cover and it passed.
Alot of newer bike with FI have no petcock so all there lines are "unvalved" and if you had a tank crossover like alot of HD's or a remote fuel valve you have "unvalved" sections of line.

[Dean Los Angeles]

Use common sense and look at your system and imagine it on fire.
The fuel shut off needs to be REALLY handy. Do you really want to reach under the tank if it's on fire? No wonder the handlebar shutoff is in the rule book.
Anything not on a shut off has to be fire proof. The safety crew doesn't want to deal with ANY fire, much less your couple of gallons pouring out with no way to stop it. Long fuel line runs can contain enough fuel to keep a fire going long enough to get everything else burning.

Nice pic.
Wonder if he has All Leather ?

(we don't need no Nomex)

Fire sleeve is not required IF you have a petcock or in-tank fuel pump.

It is required on cross-overs, if you have one.
