Fuel Injecter flow testing services

-
The injectors in one of my race engines got clogged up when I didn't properly drain the system. I took the injectors to the local NAPA and they cleaned and flowed them for me for no charge.
 
Well, it looks like it might not then.

A few years back, I found a technique on the internet to set up an inexpensive method to back flush and clean them using some common shop tools/supplies. It worked very well and only cost a few bucks to do. Then again, I had pumped some contaminated gas through them one time, so it was easy to flush out the debris.

I've got a spare set or two of those 4-hole nozzle Ford Racing injectors in my garage somewhere. I used them in a 5.9 Magnum for a few hundred miles. I had to up size them when I stroked my 5.9 to a 408.
