As for missing caps, I have pulled injectors from motors with as many as 3 different caps per set, sometimes some with no caps and even when servicing super low mileage, like 12k miles, cars at the dealership, that are mismatch. I doubt that a minivan with 12k on it had any aftermarket injectors installed, mostly because it is a minivan. lol
I honestly don't think most, if any, actually require the pintle caps to operate properly, but I may be wrong. BUT if OT says that they serve a specific function, I would heed his word.

If you measure the hole where the lower O-Ring goes into, sealing it with the lower O-Ring, it is just that, a hole of a constant size.
If the fuel pressure (36.3 psi) pushes against the O-Ring and it has no pintle cap to keep it into place, then fuel can rush by flooding the engine.
PS, Thank you confused one for having faith.
