Can anyone tell me what the numbers on my injectors mean. They are aftermarket I just can't remember what brand. Bought them 6 yrs. ago. I thought I was buying 19lb. injectors when I bought them but seeing the 26 has me wondering. 26 1147 D3800BA

 

That looks a little like a Nissan or Denso numbering sequence. Have you tried a web search for the numbers? You could also contact a fuel injector service for assistance, like www.cruzinperformance.com or any others you can find.
