Injectors Used As Garden Water Sprinklers????? Seriously.....Seems Like :\
This Much Dirt Is Only Possible If There's Tooo Much Clogged Lines/Filter And Bad Petrol Run Across Them....WIth A Sure Signs Of Rust In Tank.....Maybe Its From Old Car From Which Engine Taken Out
Anyways.....Best Is To Get Them Ultrasonic Clean For Cleaning Them Inside Out......!
By Any Reason If You Can't......Then You Can Clean Then Using Carb Cleaner Sprayed At Top Feed Side And Opening/Closing Injectors Instantly........(It Need Lots Of Patience And 2 Sane People....You Left Open Injector For Long...You Will Ruin It...)
Use 6v Supply To Operate Injectors....Don't Use 12v...
I Prepared A Small Apparatus For Cleaning Mine ANd Pressurizing Injectors With A Wiring Harness To Operate It Nicely......
