armor all for air bubbles

[spencereast]

is it the armor all original shine protectant that eliminates the air bubbles?

What air bubbles are you talking about? When asking questions give as much information as possible, for all we know you are trying to stop air bubbles in a aquarium.

sorry,fuel line air bubbles.i have heard from many people that one squirt of it(armor all original) in one gallon of fuel stops the air bubbles in the fuel line.i am wondering if it is armor all original protectant.thanks

Yes, the original. They say it only takes a few drops per gallon if I remember right. I don't use it myself.

That's common for acrobatics in airplanes since they are twisting and turning and sloshing the fuel and clunk line in all directions. A few drops of glycerin from a drug store also works well.

thanks a lot fellas.do you use it rolex?

I have never tried that then again, I never had much problem with air bubbles. Before going thru with this I would first check for air leaks in your tank.

I used it in the planes and the heli. Never want to pick up a bubble in the air. I never had a problem with bubbles on ground vehicles.

alright so it is the protective shine tho?i dont think there is anothe original armor all but jus checkin.whats the best way to check for air leaks in the tank?it is actually drying right now because today i put it in water to check but not sure.same with fuel lines.they seemed good to.any better ways to check?

You were on the right track remove tank with lines connected. Use a screw or something to to plug the shorter line sub-merge tank in water while blowing air into the longer line look to see if air bubble come from anywhere. Could also be just worn fuel line not making a good seal at tank. Also have you noticed if the problem changes with the fuel level in the tank, although rare sometimes tanks actually have a internal air leak. This is determined by the fact that Normally they will be fine when full and as fuel is consumed have problems.

lines are kind of old so ill just replace those and bubbles were visible when tank was full to so it should not be the tank right?is that what you are saying?

Yep, Armor All® Original Protectant is what I use. Not sure it's really necessary, but it does make the fuel not foam up at all from vibration. I put a squirt or two in a new bottle but I think it has a tendency to float to the top because by the time I get to half a bottle, the bubbles come back when I shake the bottle, so I squirt it again.

That fuel is trinity MHP 20%. It's supposed to have anti-foaming agents in it, but it doesn't work as good as armor all.

Fuel tanks are supposed to have some movement as well to prevent foaming. Too short of a pressure line will cause the fuel to foam a little.
Olds, I have never had any foaming issues with Trinity fuel. Just found that odd.
Definitely pressure test the tank like mentioned above.
Replace the fuel lines and all exhaust seals.
If that does not get it, check the HSN housing and the HSN and LSN O-rings for leaks.
