Mayf,
The rig that the diesel shops use to test injectors looks like a series of
glass (or maybe acrylic) tubes, maybe 24 to 30-inches longB mounted vertically
on a wall and calibrated in cc's.B An injector is placed in the top of each
tube and aB petcock valve is closed at the bottom of each tube. The injector
pump is then spun on a machine at a known rpm or known number of revolutionsB
at given throttle settings.B As diesel fuel is sprayed into each tube it is
measured in cc's. This indicates the performance of each individual injector.
A similar 'poor boy' device might be made from lengths of clear vinyl (1-inch
or 3/4-inch??) tubing available at most hardware stores and fairly cheap. A
piece of plywood, some clamps. plugs for the bottom of the tubing and a tape
measure, and you're in business.
Use gasoline and do it outside....and just be careful!B B No smoking!
