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
the period of Young and Dumb.  I sometimes wonder how I did it.

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.

Paul,
just put a length of clear tygon hose over the output end of the injector
and then the hose into a graduated container. The fuel will condense on the
walls of the tube and help eliminate the potential hazard. Just as a note, I
was at a fuel injector rebuild shop having injectors matched, and they even
used gas in their test equipment, so a direct equivalent must be hard to
find.

Sounds like that will work. Thanks for the tips.
