On the filter king pressure regulators for use with Twin 45s, how many turns should it be out. (if i was to screw it all the way in) I have no idea? I played with it and now engine wont run right........??? [:^(]
yep 4-5 psi as gary says. did you get a pressure gauge with it,guessing not? you could try one of these? maybe,i think it should screw straight into your filter king neil.
cant remember now m8 its way too much though as far as i can remember,best off with one of the facet pump really. neil.
