Question : does injector length make a difference?

12-11-2015, 04:51 PM

anyways 4 of the old injectors read less than 11ohms so I got 6 to replace them.
now the problem i have is that the original ones from the car seem to be 3-4mm longer at the nozzle than the new ones. Should I be concerned?
I did not know they have options for shorter or longer nozzle tips.

should be okay. the longer injector appears to have move ring "slot" length and the o-ring looks like it would end up in the same location anyways.

but the o ring ends up a tad higher

there is no way to lower the fuel rail? nothing to adjust?
