Does somebody have some good ideas or a "how to" for building a fixture for ccm-measurements of fuel injectors?

The reason why I ask is that over the time we got several used injectors laying around and so we want to make sure to have sets with equal ccm.

Thanks

you should be able to find something from kinsler that will work.

Here's what i build:





As you can see, a very simple (and ghetto) construction.
A cutted fuelrail, a stock Honda FPR (at 3.1 Bar = 45 PSI), a stock Honda Fuelpump in the plastic canister. Controlled from a PIC Microcontroller. For ccm measurment i let it pump for 1, 2 or 3 minutes at 100% DC and measure the volume (and/or weight).
The microcontroller let me test different DC's, too. (That's the reason i build it with a Microcotrontroller.) A direct powered injector and a stop-watch will work, too.

At the moment i only tested it with water. DON'T DO THAT! Water will destroy the injectors (rust and stuck), so i would need a test fluid or fuel. I prefer a not flamable testfluid. It could be a bit dangerous with fuel
