Injector pump screw

Im attempting to turn the pump up a little on my truck and i know you have to use a allen wrench to turn the screw the only problem is the screw will not budge either way. are they all generally like that?

yep. takes alot of force to turn it, better have a GOOD allen key or you risk having little peices of the allen key break off and end up in the pump./
