I am going to be doing some injector flow testing
in my office at home where I have a lot of test
equipment.

Anybody know of a fluid with about the same viscosity
as gasoline that is non explosive?

Hi Paul,
Must be getting old...you're getting conservative  : )
You could run a control test on one injector with gasoline.
Then use the
same test parameters with rubbing alcohol and ratio the
results.
Additional injector tests would be done with the alcohol
and apply the
ratio to get the gasoline equivalent.  Dave M



In order to attain the status of Old and Conservative, one must survive

As to the choice of substitute liquids to substitute for gasoline
which has a viscosity  of 0.4 cP to 0.5 cP at room temperature
the following come to mind.

Water                             1 cP
Stoddard solvent (Paint Thinner)  1 cP
Carbon Tetrachloride              0.5 cP

Thanks Joel.
I think carbon tet might affect the plastic in the fuel pump
and injectors. I think I'll just set up outside of the hangar.
The weather is not that bad out here. Too lean to ignite.
