Fuel crossover diameter
Well I want to put a quick disconnect fuel crossover on my bike and was wondering what the correct diameter is? The choices are 1/4", 5/16", and 3/8". Also, this might be a dumb question but is the crossover necessary? I know it connects the two halves of the gas tank up front, but the fuel pump is in the back (I think), so the fuel will get to it the same, regardless if it's there or not. I'm thinking it just allows the fuel gauge to give an accurate reading. If that's the case, then I could get rid of it entirely. Well that's just a thought. Your help is appreciated.

Almost positive it's not 3/8. I think later models are 5/16 and early models are 1/4.
You might have a point about not needing the crossover (on newer bikes) if we only rode on flat roads but what if you're going down a long hill and are low on gas?

Once you figure out which one you need by taking a measurement then you can get the coupling's here. Be sure to order both pieces.
Also be sure to get the valved type so the gas doesn't come rushing out when you take them apart. You could buy a second set to attach to hoses to drain the tank as well. The 5/16 is here.

Just about any engine work or getting at the electrics under their requires removing the tank. Sometimes you can get by with just lifting it a little and propping it up. With the quick disconnect it just makes that part of the process clean and quick. Even changing the bars can require the tank removal to get at the throttle lines or wiring or just to make it easier.
If you're paying a shop to do the work then you might also be saving money since that's less time to work on it.

The line size for an '08 is 5/16. Good thought a quick dissconnect would be nice to have on it. A dry break like the supply line, even better

You probably want these part #'s Male 5/16 and Female 5/16 Both with valves, but without panel mounting threads.
