Fuel pump failures

Ok I get what you mean now. A completely dry system. But like you said, if you actually drive your truck, you don't have to worry about things like that.

Winter gas in summer will leave your bowls dry in three days...

You need to drive it, not stroke yourself over it.

many have gotten spoiled by efi and most below a certain age don't even have the concept of carburetors.  but understand this basic. a carburetor is a vent! it cannot not be a vent. a well-ventilated vent. with some vents more restricted and some less. whereas fuel injection is a closed system, at the engine anyway. there is still a safety vent at the tank. I leave my 250 at the shop and its 351m with 2bbl. it takes a few turns to start the engine if it has been sitting a couple weeks. and a couple restarts. we have a part timer who keeps asking what's wrong with it. he is baffled when I say not a damn thing.

Well, technically (simplified) a carburetor is a venturi, where increased velocity results in lower pressure, which sucks fuel out of the bowl.

Hell, WAY back in the day it was nothing but a tray of fuel, heated on the bottom and the intake port sucked the fumes off the top.

I was going to say just that.. '

I have been obsessed with the Venturi effect ever since I learned about it. I know recently Dyson has made a big deal about it, but it has been around waay longer.

Until a few years ago I did not know anything about carburetors. When I found out the working principle of carburetor was based on "Venturi effect" there has been no turning back.

[ArdWrknTrk]

Hence 2-V or 4-V,..  even the venerable 1-V Carter YF (Aluminium)

Wait until you catch up with Bernoulli's principal!  👍

[mat in tn]

both correct and incorrect
it is a venturi when running. not running it is only a vent.

[Ifitaintbroke]

Enlighten me, Jim...

[ArdWrknTrk]

Essentially Bernoulli's principal provides a basis for venturi effect.

As height decreases, velocity increases and pressure drops, following the limits of thermodynamics..(restrict a pipe and velocity at that point speeds up)

It interesting to play with and experiment.

[Ifitaintbroke]

Same as acoustics. Pitch would also increase.

[ArdWrknTrk]

Frequency was not questioned.

Try explaining RMS or inverse square law to someone

Their eyes glaze over and they get nothing

Try explaining how a group of 16-18 year olds built a cyclotron for a senior group physics entry in a district science fair and won several awards for same, Senior Group Physics, NASA Aerospace Physics, I believe there was one other one.

So once you've done that come back here and we'll discuss the fuel pump issues you are having.

I guess until he's done that we are not going to talk about his fuel pump issues

Loving it!

Without  more input from Airtech, what are we to do?

The fact that you aren't self subscribed to threads you post, trips new people up too.
They don't have any idea there are responses.

I can't wait for Nabble to die in a fire!  🔥

[ArdWrknTrk]

Helmholtz resonance, lengths, volumes, wall thickness,  orifice size(s). 🤔

Another easy one to experiment with and have fun.

Esoteric and arcane??
Everybody needs a good pipe organ maker after the winter's tin pest comes through!  🙄

I am not Airtech, but if I was Airtech, I would maybe come back and tell us if our thoughts are helping him or what is going on. I am very anxious to know more

Perhaps he can ......
Welcome to the Bullnose Forum!  I've made you a member of the forum even though the info you got probably said we'll do that after you post.  That's because our joining process isn't working quite right - yet. 🥴😜🙄🥺😠🤣🤣🤣🤣

Let us know if the joining process worked correctly you've already been taken there, so please let us know if you have. And let us know overall how the joining process worked for you.

[Ifitaintbroke]

Ah good ole tin pest. Haven't heard of that in a while.
