I found some old injectors at the junkyard, I don't remember what the color code on them was now, but I could go and check if anyone needed to know. The guy told me that they came off of a 350 truck motor though. I had recently installed the 350, and I knew that I had to replace my old 305 injectors (TBI). I plugged these ones in, along with the new chip that I had gotten, and nothing happened, they wouldn't work. My dad took them out one night when I was at work and decided to blow them out with compressed air.

My question: What is the likelyhood of damaging the injectors so that now it is a constant forced spray? I never see them drip leaking though...

anyone?

thanks,

BB,

Given my limited understanding of fuel injectors, I would believe that there should be no significant damage to injectors that are subjected to high pressure air.

Unless the injectors were connected to a power source and actually opened while they were being "blown out", none of the air would actually have gone through the injectors anyway. And presuming that the air source was under 150 PSI, and that it was "blown through" the injectors with a standard blow gun (or even a cheater with no vent openings) that the actual pressure at the injector nozzles was somewhat lower than the line pressure. Even if the injectors were connected by fittings to the line directly, the injectors can withstand over 100 PSIG of fuel pressure without being forced open, so 100 PSI or air wouldn't likely have even entered the injectors.

After all that, if the air somehow managed to get through the injectors, I don't expect that any damage would occur.

If you really want to clean the injectors, box the set and send them off to Cruzin' Performance. There, your injectors will be tested, cleaned as necessary, and flow-matched to better than factory specs. You'll get new inlet/outlet screens and a bill for about $10.00 each plus shipping.

I've had excellent results from them more than once.

cool, thanks. I'm not sure what the pressure was coming out of the compressor, its really old, belt driven. It'll hurt your hand coming out, I know that much. but they were unplugged at the time. I think that the problem might lie in that they may be the wrong injectors.
