Tim
Probably 5 or 6 minutes.
I'll do a flow test and get an exact time soon.

Is pump pressure critical?
I would like to cobble up a smoke system, and the info you have provided is very helpful!
I have a Holley electric fuel pump PN 12-802 (for a race car) laying around the hanger unused, and I was thinking about using it for a smoke system. But, the Holley spec sheet says it is internally preset to 14 PSI, I notice yours is 60 PSI... Would 14 PSI work, do you think? Would I need to have different size orifices to inject the smoke oil into the exhaust? The flow rate is more than adequate (somewhere between 70 and 110 GPM at this pressure)....
Thanks,

I think my 60 psi is way over kill, so I'd say try it and see.
Good luck

In cold temperatures, the vegetable oil will get extremely thick. Besides you'll come back smelling like french fries

I have seen smoke systems on Pitts Specials that used a mechanical fuel pump for the smoke oil (the same fuel pump that is on our RV's). The pressure is close to what your electric pump is set for. It seemed to work just fine, and was reliable.
Good luck!

Hey Jon!
How ya doin?
DO NOT use jet A in your smoke system! It may work but if the nozzle ever breaks or the fuel is otherwise vaporized and his the exhaust, you will put ou a really neat trail of flames!
I dont think you want that. Ask me how I know.

Also, using flammable liquids is not only dangerous to you, it is dangerous to those "who choose not to smoke". Inhaling unburned fuel vapors is dangerous. There are better, safer products to use that are certainly better for the environment than jet A.

but I believe Jet A is the same as #1 fuel oil...which has a closed cup flash point of 100F...in other words technically Jet A is combustible but not flammable.
The question is..is it combustible enough to catch fire in an exhaust pipe?...It looks like it may well be.

smoke injection nozzle
Does anybody know what the smokingairplanes.com guys use for nozzles? I like the idea of not having to weld a bung on my vettermans...as a matter of fact, I just spoke with the vetterman folks and they recommend against it.
If anybody knows where I can get the clamp on type of injector nozzle, I'd appreciate some details.

smoke nozzle source
I got mine from Earle Parks at Parks Industries (806) 622-0602. They do work on T-34's. They are not cheap. If memory servers mine cost about $45each. I have had mine for about 3 years now.
