cleaning injectors can it be done?
I found my injectors stopped up with varnish. The car had been setting for 4 yrs.I had 43 lbs to the rail, put light on injector harness and it blinked as the starter turned over, ok I pulled the injectors out put 12 volts to each one as I sprayed car cleaner thru them then sprayed air thru them as they were held open with the 12 volts. Will this work for cleaning them?

Re: cleaning injectors can it be done?
I did the same buddy. I pulled them out, connected a little nine volt battery, and sprayed just a little. I really dont know if its good or not because yes gasoline is harsh on some rubbers and plastics, but as we all know, carb cleaner is a very powerful cleaner and it can destroy rubber. My point is, I dont know if it (carb clearner) is to "acidic" for the little rubber pieces at the tips of the injectors. It did clean out the injectors, but as soon as I get my engine running, Im going to dump a fuel injector cleaner, fill up with supreme unleaded and dump octane booster. Then hit the drag strip, just to clean the sh*t out of the fuel system. I highly suggest your have the injectors serviced at a shop that performs ultrasonic cleaning techniques. Check out this video to see what Im talking about............. http://www.youtube.com/watch?v=ZJmdvoZ83hY

Re: cleaning injectors can it be done?
Give some of these a try. I did make my own years ago with an extra set of fuel rails ,extermal fuel pump, etc.

Re: cleaning injectors can it be done?
Thanks TPI I will try your way of cleaning them money is on a tight budget just to move a car. If I decide to keep the tpi I will invest in some injectors later when economy gets better, and that could be a while Thanks again

Thanks Thunder didn,t know that. I am new to this tpi stuff, makes a carb sound better every weekend I work on it. But I would like to get it running to see if I want to keep it original.

Re: cleaning injectors can it be done?
Thanks for the reply. I scored a set of two lt1 fuel rails with injectors for 50 bucks. I havn't seen them yet, but they were running pulls and I am going to replace my stock injectors this winter when I do the valve stem seals.
How do you recommend I check? Do you sell the replacement filters?
Thanks!

Re: cleaning injectors can it be done?
we sell the filters, but we will just send you a set if you decide to change them out. Just PM us with your address, but Just know that changing the screens is not the answer to a "clean" injector.

Re: cleaning injectors can it be done?
Wow, that's really nice of you!
I realize this.. I know that I really should have them ultrasonically cleaned while being pulsed, but I just moved out on my own and am on a killer budget...
How much do you charge per injector? I'll have a spare set, so maybe i'll send you a set to work over with my tax rebate!
