Tips for renewing O-rings and pintle caps on E30 fuel injectors without tearing them: the seals are hard to stretch over the caps, and the author insists on new pintle caps every time because reused ones can work loose into the intake.
Tools mentioned: Pick, O-ring/pintle cap kit, light oil
Quick tip for cleaning injectors: thread a screw into the inlet filter, clamp it in a vise and rock the injector to pop the filter out; the new filter is pressed in and tapped home with a rubber mallet.
Tools mentioned: Small screw, vise, rubber mallet
