U just unplugged a vacuum line or loosed a rubber vacuum connection. Just snug them all up. Especially chexk the one on your shut off valve with the brown air line, with a blue (maybe grey, don't remember) stripe. Because that one is connected to the far right of your injection pump


I would suggest replacing them all with brand new ones, one by one so u know which ones u replaced and don't miss one.

It take 15 mins and will help in future.
