Looking for cock information

[Priv]

Petcock information that is.... I'm not sure if I'm going to need a new one for my fuel tank. Went to dump the fuel out of my 250's tank and ran into a speed bump. Tipped the tank, and turned fuel to on, and watched no fuel empty. Then opened the cap just to be sure it wasn't a vacuum issue, and again, no dice. Is it possible that the petcock is clogged or something to that effect?

On the valve, does it say "prime or pri" on it? If it does you have a vacuum operated petcock and in order to get fuel out of it you will have to turn the lever to "prime or pri". There would also be a small hose connected to it along with the main fuel line.

Just took a look, and mine doesn't say either of these, just the usual on, of,f and reservoir options. Thanks for the info though

It does however have a small hose and a main fuel line.

Take the petcock off the tank, then let it drain through the new opening.

The small hose is a vacuum hose. Needs vacuum to allow fuel to flow.

Concern is if the petcock is operating properly or not. I'm just concerned that we get the carbs all cleaned up and ready to be sync'd and the petcock is garbage and then we'd have wasted ours and someone else's time when we could fixed the problem now and be ready to go.

So hooking up a hand vacuum pump will get it moving?

Do you mean the entire thing? it does look like one of the hose connectors is removable....

Yeah, doesn't take much vacuum to operate the petcock. If the petcock is a concern I'd open it up and inspect it, real simple assembly. The primary piece is a diaphram that shouldn't be cracked, dirty, torn, etc.

Don't lose the spring!!

It probably works fine, just need to put some vacuum on it to check.

Yeah it probably does work just fine... the small hose is attached to a vacuum source... the big one is the main fuel line. Clean the carbs or whatever... a lot of people with ex500's put inline filters on there because there is no fuel filter from the factory.. not sure if the 250 is the same way. Something to keep in mind.

You can use your "Special" Pump But clean it first

You think I want another cock in that pump?

You're going to have to suck.

It will only take a few inches. (ha ha)

[scottfromboston]

You're going to have to suck.

It's easy enough to create vacuum to prime the system by sucking on the small hose; it's isolated, so you're not breathing fuel. YMMV.

Then again, I've had plenty of practice sucking at life, so a little hose is no issue for me.

EDIT: Oh, you're trying to drain the tank. Yeah, that would take forever - pull the petcock off, or find a vacuum pump.

When i drained the tank on my EX500, I just turned the petcock to reserve, sucked on the vaccuum hose to open the diaphragm, folded the hose over on itself & used a clip to keep it pinched.

Took a while to drain it, but it worked.

...petcock... ...sucked... on the ...hose...

Can you say that again, but slower?

The 500's dont? My EX had a filter connected to the petcock, on both the reserve and main lines.
