I thought I'd start a new topic for this because I'm betting I'm not the only one who seeks this info.
My 25 hp v-twin Kawasaki engine has one of those black plastic pulse diaphragm fuel pumps that operates off of vacuum. If I take off the discharge from that pump and turn the engine over, or just start it, can someone tell me how much pressure or volume is normal at idle speed or full speed? I found one video on youtube showing the flow as the starter turned the engine over and my fuel pump doesn't put out even near the same volume.
I was looking for specs on these, or at least a layman's description of its output volume /pressure.
thanks,
