Fuel injector pintle caps ???
Does anyone know if the plastic pintle caps on fuel injectors is really necessary? I'm looking at some SVO injectors, but the caps are different & I'd need to take them off. I had probs w/ my stock 280zxt injectors when they had broken caps... but many people have said they run w/o them.

You don't need the pintle caps for the SVO injectors. Most people pull them off. The o-ring that the SVO injectors use seals perfectly fine, and will not cause a vacuum leak like the stock ZX injectors will if the caps are missing. I'm running my SVO's with no caps on them and I didn't notice any change from when I had them on.
