I'm looking for some inline connectors I can put on my fuel lines that seal when they're disconnected. The stock connectors are okay, I don't think they really let much fuel spill out, but when I have my tank off for a while (like while I adjust my valves), they let plenty of fumes out, and it makes my whole garage stink!
I found these here:
http://www.aerostich.com/gas-line-quick-disconnect.html (http://www.aerostich.com/gas-line-quick-disconnect.html)
Anyone know if they would do the trick? They have two sizes, 1/4" and 5/16". Anyone know what size ID our fuel lines are?
I have the motion pro ones. They work fine. I don't remember which size.

Nice... does the single shut off mean that only one side is sealed when they're disconnected? I wonder if that's how the Aerostich ones are as well.

I'm not sure, but I *think* that's right. That was my understanding, at lesat. I've got the dual shut-off.
It helps if you attach them so that one lines has the female end on top and the other line has the male end on top (yes, I know how that sounds). That way, you won't get the lines crossed when you reconnect.
They are a bit cheaper on mcmaster (depending on what design you use.
but i still want to know the inner diameter of the hose before i order. i want to get 2 sets, so i can swap between my plastic and metal tank.
$29.99 is a bit steep. but a lot of things from motion pro, however they have high quality stuff so you are getting what you pay for.

Anecdotally, one of MP quick disconnects failed on my bike after two years. I replaced it. Dunno if that means anything. If I had to do it again, I might go for the metal ones, but I'm not sure where to get 'em. I can measure mine (the disconnect, you sickos) this evening if neither of you guys gets an answer as to the proper size before tonight.
I just bought a set of metal disconnects with the auto-shutoff feature for my 996 for $50 from:

the OEM plastic ones from the dealer would have cost like 3x as much

I did that so it was idiot proof. And so far, I see that it's working. ;D

Well, I tried suckin' on one of 'em to see if there was bourbon inside, so you probably should have attached a label to the lines or disconnects saying, "NOT A STRAW."
which end were you sucking on? the female or the male end? ;D
sorry i was waiting for the right setup.
Seriously though, the ones that bones posted up look good. about the same price but in metal :)

I tried both. I was 'experimenting'.
My experiences with quick connects has been poor , i have tried seeral brands ,plactic and metal all failed very quickly .
On my S4 I have put an inline fuel tap on so i can stop fuel flow when tank is removed .
Nice! Those metal ones are pretty cheap. Now, does anyone remember what size ID our fuel lines are?
I'm running 5/16" on my M800.

jerry,
What inline disconnects are you using? I've got an S4 and I'm about to swap tanks and would like to put auto shutoffs on so I dont have to worry.
As far as quick disconnects for other bikes Omega is the company that most retailers source them from, you can buy them directly at half the cost here:
http://www.omega.com/pptst/ftlc.html (http://www.omega.com/pptst/ftlc.html)
jerryz, why has your experience been poor, aside from poor quality parts that can fail, i dont see how they can suck.
Well, that may be it, He Man, they do not suck, but they make it harder to blow. I'm using them because I tinker and they are convenient, but I'd rather not have them. Here are some for instances:
They reduce the hose effective flow rate from 5/16" to 1/4".
They further reduce the flow rate with the one way valves.
The acetal material is rated for 180F. This is probably for the liquid temp and not environmental, but when my oil temp soars past 200F, I have another thing to worry about.
The butyl O rings are easy to tear when you connect/disconnect. Then you have a leak and need to find replacements after you siphon the gas off the bike.
But what I really dislike the most about them, is that they are long enough to make it hard to have a smooth curve in the hoses from the tank to the injectors and regulator. I have found it easy to button the bike up and have a kink in the hose, reducing the flow even more.
Mind you none of these things are dealbreakers, but they add to the preflight checklist.
So, is there any alternative that anyone knows of? I just want a way to not fill my garage with fumes if I have my tank off for a day or two while I'm working on stuff ;D
its not going to fill with fumes if you empty it out. lol
so does anyone know the ID of the fuel tubes? im about to put in an order at mcmasters and figure id pick a set up.

That's not a change in flow rate to be concerned with on these motors, the change from 5/16 to 1/4 is insubstantial here.

Okay, ill admit, i was scanning through it. :-[
5/16 it is.
Hey, its 5/16.
That's funny ;)
actually its 5 times the summation from n=0 to n=infinity of 1 to the n over 16.

sorry i did not answer for a few days , i tried MP, BMW, TRD , lockhart Phillips and several unbranded ones and a few i cannot remember the brand , Pressure was a problem also Gasohol damaging the O rings ,they all failed eventually .a stainless and brass inline tap solved the problem i can stop the fuel and remove pipe and then tank ...easy and bulletproof
