Thank you i will probably go with the 2.5-4.5 psi pump then 30 GPH should be enough, I just wanted to get a guideline as i had no specs on the electric fuel pump on it now or the factory pumps. As far as fixing the factory pumps I tried once and failed when i bought the motor it was running on an electric pump and had the factory pumps bypassed I bought new diaphragms and check valves and ran new lines to the factory pumps and it would run out of fuel and stumble at times so i just went back to using the electric pump as it solved my problem. I am not sure however if i had the lines to the pumps ran correctly, there were no lines and i assumed that the two pumps were plumed in parallel and that is how i ran them but now i think the factory pumps were connected in series originally? Anyways i'm going to stick with the electric pump as i use it to prime it and don't have to mess with the primer ball however i did leave the primer ball in there as a back up get back to shore pump. I do have my pump wired in so that it only runs when the motor is running or when the electric choke is activated to prime the fuel system. Thank you
