I just got back from Fuel Injector Corp in Livermore, CA. The injectors all had the same flow rate and also had an excellent pattern. Robert put 3 new o-rings on each injector. The flow rate that most peopel read about is 145 ml/min. But that’s only at full open. Mine were also checked at the equivalent of 3k rpm, with 43 psi fuel pressure. The seal that goes between the injector and the intake manifold had tiny cracks in it on the lip, at the very top of the seal. So I had to order them from Honda. They are a rare item so it was going to be 3 days. So I had them expedited and they will get here tomorrow for $12 more. The seals were only about $4 each. I could see reusing the old ones, but with 220k miles I am just not going to do this work twice. So the Insight sits for another day. I’ll go get them and the o-rings for the intake manifold in the morning. I may take the egr plate back out since it’s waiting for o-rings anyway and use some solvent and q-tips to polish up the passages a little more. Depends on how energetic I feel. We have plans tonight so I may not have time. Regardless the egr plate is clean and will help the Insight run far better when it’s finally back together!
