The actual "liquid" is never the part you need to worry about ----- it's the FUMES that can be easily ignited.
If you think mixing electricity and flammables is a dangerous idea. Please don't drive your new vehicle as the fuel tank has an electric pump inside of it smothered in volatile fuel.

They also have a stoddard type solvent with a 140 F. flashpoint. It is (according to the S.K. rep), safe for all electric pumps. At this point, this is what I have decided to go with. It is about twice as expensive as home store mineral spirits, but if it is far less flammable, I am willing to pay it. I just can't get comfortable using highly flammable solvent in an inexpensive pump with electricity in the mix.
As it turns out, S.K. has a home user promo going on where they will come to your house & fill your parts washer with up to 10 gallons of either product for $99. The contract calls for a replacement in 6 months where they will recycle the 1st 10 gallons, and refill you for another $99. So, the commitment is $200 & you should be covered for at least year. I'm not sure if I will use the washer that much, but I can't use it at all empty, and this seems like the safest path.
As always, any input is appreciated.
