Topic: Leaking fuel

[txterror]

Recently i have felt bad for letting her sit so long and now trying to get her back on the road.

Last night i went to start her and she started to puke fuel. Upon inspection i noticed the fuel was coming from one of the nipples between carb 1 and 2 (carb1 was leaking)

Purchased bike in 2012 and carbs have never had these tubes connected in between each carb. I have ridden her many times before and never had fuel come out from there. I purchased bike like that. I think i have even posted a question about them before, but its been so long.

Do i have to disassemble carbs in order to get line on them? pic attached to show the tube I'm referring to.

Appreciate yalls time and experience, as i am still learning.

Are you sure it leaks there and fuel doesn't come down along a tube from above?

Saw it with my two eyeballs Delta, had a pretty steady flow.

Those orings can dry out when the bike sits.
They can also swell a little when back in contact with gas.
IIWM, i'd set up some sort of catch for the dripping gas, and give it a day.
They might correct themselves.

fuel only started coming out when i turned the petcock on flybox. My carbs don't have the tube(line) between each carb. Nipples are exposed

Thought you were talking about the T connectors
Its been a while since I had my 350F(same carbs), but IIRC, those look like the atm vent tubes.
If fuel is coming out, you have an issue with your floats/float valves.
Someone will chime in, but either way, you should have fuel line on them.  Just pinch a new piece down in there

Yeah those are just the air vents.  Just equalize pressure so that the bowls can fill and empty out properly. 

If you have fuel coming out of there you have some problem that would need further investigating.  I don't really know how fuel even gets up there to come out.  It should be coming out the overflow tube. 

Anyways, you could put the two hoses on for each side, but gas isn't supposed to be traveling through there anyways, just air.

That's why I asked if you're sure sure it leaks there. It seems odd.

Nice polish on those bowls! if this is a pic of your carbs, I don't understand "nipples are exposed" - the fuel connector tube between 1 and 2 is visible.
Anyway, the circled part is a pressure equalizing vent line that links the fuel bowls. No idea why that's needed, maybe a backup path in case one or more of the bowl vent tubes gets blocked?
If one bowl bottom nipple or its tube IS blocked - plus it happens to have a bad float valve - fuel could get that high bu...t would also pour into the throat, I think.

Thanks for the replies guys. Got the carbs off and mannaged to get some hoses in between 1&2 and 3&4 but left th two that face up in between 2&3 exposed. Got the carbs back on, turned the fuel on and fuel began to pour out of drain hose on bottom of bowl 1l. What would you guys suggest? Float looked fine but looks like carbs are coming back off and I'll be buying something once again.

Also If I do run hoses from the two exposed nipples pictured where do they run then to? Do they run to the bottom with the rest of drain tubes?

Try draining the fuel out of bowl 1 and then turn the tap on again - this may flush some crap out of the float valve and fix the leak...
On my bikes those two breather hoses run up to the rear and terminate in the area at the top of the battery.

That's more like it. Start with the easiest.
1. Do as Jonda suggests. If that doesn't work...
2. Tap floatbowl with stub end of screwdriver. Maybe floatneedle frees itself and closes again. If not...
3. Remove floatbowl for inspection of the floatvalve and needle. This can be done with carbs in situ.*
