Vacuum Pressure Bulb for Combustion Gas Test?

[jaymar_]

Bought a kit, doesn't come with a bulb. Anyone know where I can find one that will work in this application? Not even sure what type I'm looking for. Everything I see is medical or scientific. When I add automotive to search, I wind up with light bulbs... TIA!

Needs to work with this:

That one is made to hook to a vacuum line on the engine. Any bulb that you can adapt to.the hose.should work. You just need to create some suction. I went with the view two chamber tester because it is less likely to give false positives.

Videos I've seen with this, the bulb is sitting right on top of the main piece. No idea where they got the bulb, though...

I just googled lisle 75500 and didnt see any videos of it being used with a bulb. A harbor freight one did pop up on the search. All the other versions besides the lisle 75500 use a bulb, that one uses a vacuum source.

Do you have a vacuum tester?

 

[jaymar_]

Damn. No I have zip; just what's in the package. Didn't know about the dual-chamber ones at the time...

Turkey baster?

Turkey baster?

You know I've been wondering about that?

Anything that will pull air threw the fluid will work. If you are desperate you can even **** with your mouth, not sure how good it would taste though. Since you already have the lisle one use it as an excuse to pick up a mityvac vacuum pump, also good tool to have on hand.

Turkey Baster seals and works! MityVac is on the list...

As said, a turkey baster works. The camera blowers can also be work pretty well.

These are about the best I've found for gas analyzers. They'll work upstream or downstream of the instrument.

if you have an old coolant cap, drill a hole and run clear tube through it, do not submerge, run the other end into a coke bottle with the test fluid.
Start car cold and wait for it to start bubbling (in the coke bottle) as the air in the tank expands.

The bulb from an outboard engine fuel line would also work if you have one.
