I changed the fuel pump on my 345 18 hp v-twin after a failure and ran the mower for an hour and then it stalled. Acts like classic vapor lock issue. I checked the vented cap, changed filter and ran all new fuel lines to eliminate any line colapse etc. Also checked the pick up line in the tank for cracks. I can start it and shows fuel in the filter and after about 30 seconds or so it dies, I pull the line of the exit line side of the pump to burp it or check for gas and it will start back up for a short time and die again. What is the pump rated for in volume so I can check it to see if it is putting out the correct amount to feed the engine. It acts like bad pump but also acts like vapor lock. Any ideas ?
Thanks, Martin
