hi guys i bought a smoke system yesterday and have it installed only thing is the tank. do i have to have a breather because the way i have it set up it only has one pipe going in which i would guess its going to vacume the tank. but if i put a breather in its going to come out of it when inverted or any old way and ideas. i suppose i could put a check valve in do you think this will solve it?

You don't need a check valve. You won't really lose any if you have the vent tube exiting the bottom.

You need to double-tap the muffler. If you T to the muffler pressure line for fuel, you will pump some smoke fluid into the fuel tank every time you turn the smoke on.

Its no good for the glow plug.

I know its not going to be a lot of oil going into the fuel... but its a fuel contamination and you don't want it.

Maybe I should have been more specific...

Yes, you need a vent in the tank, but no, you don't need a check valve in that line providing it vents out the bottom (but then, where else would one vent it? )

seems I misinterpreted things last night.[&:] Yep there has to be a second line to the tank to let air in.
