Sometimes resin doesnt transfer all the way through the part… instead of waiting till the end. what about this
getting a syringe with a big needle tip.
then getting some yellow sticky tape to act as a barrier to stab through and also stick to the bagging.
put resin into the syringe, with no air inside of it. tap it =)
plasce the sticky tape on the bag, and then slowlly stab the sticky tape/bag and squeeze the resin into the mold. this should work. =)
well…
yeah…
But why not just have the correct positioning for inlet and vent lines? 
So let me put “For Emergency Use Only” =)
Oh, well in that case…SUUURE!
Good luck getting the resin in the syringe. Always had a hella time doing that. (used it for spot repairs of parts and getting it in tight spots)
I’ve heard of a kind of similar technique for filling larger air bubbles in a cured fiberglass part. Drilling a tiny hole into the air bubble then injecting resin into it. This however is different than what you are talking about Luisn. I’m not sure what i heard is good info or just some lame idea.
Why not just include an extra feed line or two half way through the part? If the first feed line doesn’t infuse all the way, open another feed line. Infusing each and every mold is different, but once you master a specific mold, you will not need any “precautions.”
