Perry Pump question
 

I have a perry (newer conley oscillating pump). It is the VP 22SG. The package states it is for Gas and smoke. I originally bought it thinking I might experiment with smoke. It is still unused in the package. I am wondering if I could use it on my four stroke engine as a standard pump for the engine instead of for smoke? The perry home page sells another version of the pump for $2 less. The "SG" identifier says the internal parts have been modified to be used with Gas and smoke. Can they still be used with Glow fuel???

Anybody out there know for sure???

Thanks for the heads up.
