Ok I've tried adj. The pump for the second time can't get the screw to turn left or right. Anybody have any ideas..

 

what screw u trying to turn? the one inside the pump?

 

Yes the one inside the pump...allen head

 

it does take a bit of force to turn it. thats why we say to use a GOOD quality allen key.

 

I had to hook a damn vicegrip to a allen to turn it just dont go overboard and break somthin

 

If it's really hard to turn, I would try turning it backwards first so you know how much force will be required. If a PO had already maxed the screw out and you try forcing it more you can do serious damage to the pump.
