Already have press req and qauge, and I did soak it for a few days now, tomorrow will put the 12 volts to it from one can to another. Sad thing is I will have to drain my tank before install, want to change all the old line out to the pump with a new one, in fact maybe I`ll just change it all out all the way to the motor sinse there is a union about half way up that I did many years ago, opinions wanted filter canister before pump or after...?
