I have a new pump tank,relay sounds good and both pumps run, the idle is still going between 850 and 1000 rpm. It starts and runs but it used to start hesitating at take off after 2-3 miles then it died after about 10miles and restarted in 10 minutes. Is it the main pump,which I contiue to hear even after starting?
