The new Bosch fuel pump I bought on ebay several months ago(NOS pump from a
Porsche/german car shop in California) had been filled with mineral oil to
prevent what you're afraid of.  Can't imagine 5-6 oz. of mineral oil
gumming up the injectors, especially if you dumped 1/2-2/3 of it out before
installing!!
