I'm expecting some new injectors, so in readiness I removed the old ones and removed the nozzles, incase I need to re-use them in the new injectors.
Whilst I was cleaning them I noticed that two were wider than the other two?
I measured them and two are 2mm and two are 3.5mm. I am pretty sure the two larger ones were on the two outside injectors i.e 1 and 4.
Is this normal or an error and what's the logic for having two sizes?
Has anyone come across this before?
