Hello everyone,
I decided to refurbish the fuel rail and fuel injectors last night and figured I'd post the results: First the fuel rail was disassembled and all the components were cleaned in a variety of simple green products. In my opinion one of the more satisfying aspects of this rebuild is making something look new again. That was definitely the case here, I wish I had taken a before shot to show the contrast.. Next all of the hoses were replaced with fuel injection and vac lines. Finally I turned my attention to the fuel injectors. Normally you would just send them out to get cleaned but I was inspired to try cleaning them on my own after watching a youtube video showing a way to cycle them with carb cleaner and a battery. In my case I had to be careful because the st205 uses low impedance injectors, which means a large current will cause damage to their solenoids. In fact the gt4 harness has a resistor pack built in to step down the voltage to avoid exactly this problem. Unfortunately there was no way for me to tell what voltage these injectors actually operate at since my resistor pack was not labeled. Therefore I had to start small and wire AA batteries in parallel until i got a response from the injectors. Eventually I switched over to a single D cell battery and got the injectors to actuate. From there it was a matter of connecting the injectors to a can of carb cleaner and cycling them until I was certain they were clean. I had to flow the cleaner backwards since these are side-feed injectors and my options to connect them were limited; still I should get the benefit of flushed screens that way. I recorded a small video demonstrating the process. Its crude, but effective. http://s74.photobucket.com/albums/i277/sub...nt=MVI_1188.mp4 I still need to purchase new injector o-rings and perhaps a new fpr before the fuel rail is complete. But that's gonna have to wait until some more funds come in. Anyway, next week I should have the cylinder head completely finished at which point I'll be taking the block apart.
