Dunno if that makes sense. I'd like a small device (doesn't HAVE to be a float bowl, but should maintain a constant fluid level at ambient pressure). Where can I look? Alternative, what brand of crack should I change to?

How small? Smaller than a float valve out of a toilet?

Can't help you with the crack thing...

I've been looking for a beer mug that works as you describe, so please let me know when you find the answer. : )

What do you ned it for and what size does it have to be?

I need it for metering water in a water injection setup. Something the size of a small carb's float bowl would be nice.

Blake - Why'd you have to mention that damned beer mug? I don't even LIKE beer and I'm now visualizing various implementations of Blake Mug.

Saro,
Why not a float bowl? Any Holley carb from the sixties to present has a nice and easy detachable bowl and metering plate. Lots of scrap Holleys around. I also used to have a steam furnace that had a water supply that was automatically supplied via some kind of sight glass float dealy.

OC-

Why not a float bowl from Any Holley Carb? Really, it's because I'm an ignorant dolt and didn't know Holley carbs had detatchable, workable, float bowls! I guess it's time to look around there now.

Next question: Any guesses as to how typical float bowl components might react to long term water exposure?

As far as the water issue a couple coats of clear laquer should stop that problem. Also back in the late 60's/earley 70's they made a float bowl/fuel pressure regulator for some sort of auto use. I used to have one but cannot remember who made it or where I got it, and no I do not have it any more.

Saro,

I once implemented a water injection system on a turbocharged engine. It used what amounted to a windshield washer pump energized via an intake manifold pressure sensor/switch. It had different sized jets for tuning the amount of water. That was either full on or off though. Sounds like you may be looking for a continuous metering system?

Blake-

You got it right. I've been itching to try something for a long time and I'll probably have the chance soon. I'll likely post about success or failure after I run it.

My main goals are centered around simplicity and clean installs. I'm just not certain how effective this style of system will be.

Time will tell.

Feel free to bounce it off me offline if you are hesitant to make it public.

Why can't you use the operations like the dog bowl watering bottle. Just apply that theory with a supply into a closed reservoir with the capacity you require. Just a shot in the dark.

Joe-

Interesting idea. Seems like a good way to at least try a few things, but in the end it seems like there'd be lots of opportunity for variation of fluid level plus some complications while filling it.

Still, I'll likely give it a shot as well!
