Jim S. > --------------------- Jim makes a good point, but it can be carried a little further with little effort. I have attached a GIF drawing, showing the plumbing modified to feed the pump from a reservoir, pump through the engine and rads, and back to the reservoir. With Todd's setup, this would be easy to do. Also, since it is electric, you can turn it on and off easily. A simple timed test, where you divert the water from the reservoir into a separate bucket and measure the time for filling would give you a number for the flow rate as well as the visual test that Jim mentioned. The change in head of the reservoir can be minimized by making it larger, but probably not a big deal. Since the pump is electric, you can just turn it on, and then off at the same time as a stop watch, and get some pretty accurate numbers. This way he doesn't have to take his assembly apart (other than one connection) Bill Schertz KIS Cruiser #4045 --part1_e.26cd4d1a.2adac486_boundary Content-Type: image/gif; name="Electric Pump test.gif" Content-Transfer-Encoding: base64 Content-Disposition: inline; filename="Electric Pump test.gif" R0lGODlhkAGQAecAAP///wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACwAAAAAkAGQAQAI/wABCBxIsKDBgwgTKlzIsKHD hxAjSpxIsaLFixgzatzIsaPHjyBDihxJsqTJkyhTqlzJsqXLlzBjypxJs6bNmzhz6tzJs6fP n0CDCh1KtKjRo0iTKl3KtKnTp1CjSp1KtarVq1izat3KtavXr2DDih1LtqzZs2jTql3Ltq3b t3Djyp1Lt67du3jz6t3Lt6/fv4ADCx5MuLDhw4gTK17MuLHjx5AjS55MubLly5gza97MubPn z6BDix5NurTp06hTq17NurXr17Bjy55Nu7bt27hz697Nu7fv38CDCx9OvLjx48iTK1/OvLnz 59CjS59Ovbr169iza9/Ovbv37+DDi/8fT768+fPo06tfz769+/fw48ufT7++/fv48+vfz7+/ //8ABijggAQWaOCBCCao4IIMNujggxBGKOGEFFZo4YUYZqjhhhx26OGHIIYo4ogklmjiiSim qOKKLLbo4otiBSDjjDTWaOONOOaoo4wwnhTATT/2WFKQNREppEhGzpTkkR8tGZOTTHIE5UtT RplRlS1haaVFWq7U5ZYTfZmSmGBCRKaPZXp0pklrprlQmyTB6SZCciI550Z1hpRnWjv26eeN rO3ZpFMzGiToQ4ciGiiQhALwI480OvpooZFeOeaiNiWqJKSPSuppp5xqpGlDoz5WqqVNgWqj pIDyiCqaq53/ipGsYNFK52d/AvnnjmfZepCvb/lJKqMXATtUkrvuaqhkghor0Z7OBoWslMtG 1iyxXPZakKZLRrvWtZnOqmayrlJEbo0KTYtntZCBm265Q4rb0Zl1wlmluqKya+qrCanK6qSe XnkuvuuamW2Y6W5LrcLWGjowQ5Sy6ujE8Bb7LMMLK1qRvQkTxK2+jnV78ZuQBqzqoWsSnK/B G5vb8UAfY7yvzA61WShIKdPM77AtI9yvzgd7zCzIPBc5MsxqRlSvyz8LXZvISmOrMdLzRt3z 0b8C/RrULBttNdUZ1xz011k7TRvXU9OUs9kFp41112WDPRvaYodLtkCj0js23CB7/xsy0RBL XTfbOwd+9d00+90Y3UWr/fbEYTf++OBx420b44Z7zTfkbVM+ueSJ9zvwuYdh/qbgoOeN+Oae h37rSIp3ZfrLjiOuOutu5074lMDGztXsTWue++26F5955ZwDXrVhwL8ufOvEt4778X0Hr2fp ytOu5OPRgz796dYnr3XkgjWPvExrEy6v8d63b7n6cuOM/fjho8/98uxTz77K8ONPmPnZc0n6 4rc+6eWvfrtDoP8GA0D6ZYl7o9OR0iJYMUTxqn/iGxTzAui82n1vZQfUXggJSMIFlo+D53vS 58gHPqatMIXvs9MGHQhDKr0QhAbMYQvd17v5YVCBNlydCf93eEMg1rCHM/xhB7cnRBaK8ING zB4SC9NAj1HwiheEYgHdx8UnAnGK/0NhVLCYKzNd0VzkimLhAlPFuejtcFrs4hoB00a5vNGF TcwjDhkoxrrc0WdF1OEeT0hDu/wxkDXU4xz/Use4HFKRS4SjBqnYR7o8Mo6VJOIkw1hIP0JS jZHEo/ySWEK9XHKEmfSiExmZSkd+MpRyFOQi/dJIuJxSlrBE5N4IqcS73DKWicSkJNnYSlu+ MpigBOYuidlJSx6zmBkU5Sb52Ew3PrOavcSlxUgZQ1YKE5ooi5MPS5mXX+pPm+d8F5l8t5Va Buua2UQmOi0HsEhRyp7stIo73WL/Tk3OU5V0KpnEKOavfOoTmvyEJzkB+s2CRoygAuXlQn2p 0G5+M5nLpCNC29JPhmLUn0PUKDZdedF4btSkwxQpSu1Y0WgqE6SrpOVJv9VSjs1ykMxcKUlR Kc+epjOmfdknR2sqzaKG1Js6NWZJJ5rLlv7TkDNVS0c/mlSfphSpTPXkUi3KU49uUaJc5ctU m+rVlxoVq2Hdy1itWtWowlSmI1VqV+PqUl1eFa5tHepW6/rWvT5Vq3lly1rBidOj4jWrztwr BQsLVLG6FS0PKwoYqRlY4kwWrHyNzmVziljmbFalnV3OZ9GaWeiM9rBpnc5pg/pY4Kx2Vlms ilCL89ow/91MnWTMrW5x1Nrf1NaMaMyKQTElQ4HB9irDjZU4j4un5C43O78tq12J4tzURPdX tqogU6qLmuvSdbpA4e5pvBtaLu32vGTcDnp5C96vlol/21SJeBME37s+N031PWu85pTf9hpW SP31a+e2FOC5jvK9361sY11UYLPCDr8JTu0DwdTgvnoJwYGdr4QZHGENl5ZFFaYqrKwUYrJO mMQJ9vCGQZxinajYPyXu7X+vs94anzGvL/awjXfM4x7XuJ0ZNa+Ph8zeAS0tJy82cpBVyN8l wyTJAjoyTqAcICmjLjxEznKRAXll9Gn5y2AO822lOi4xE5lDOr7TTU+sZvuyuf/NXPYgnPXL EipvaL52vrOc5+xmlOQZzfbj85rZJGjGjrjQ7j00ouN74UUburiOHvSMI+3USlNaxia+tG2R 9GcWT1PTTeJWp3uk3QmCWr72GjWFxxzQUp/aS7F9taxnTeta2/rWuM61rn3r6l3X+VMl67Wv ceZQig3bz3i7p7GP/SRVM/vZ0I62tKdN7Wpb+9rYzra2t83tbnv72+AOt7jHTe5ym/vc6E63 utfN7na7+93wjre8503vetv73vjOt773ze9++/vfAA+4wAdO8IIb/OAIT7jCF87whjv84RCP uMQnTvGKW/ziGM+4xjfO8Y57/OMgD7nIR07ykpv85CglT7nKV87ylrv85TCPucxnTvOa2/zm OM+5znfO8577/OdA70tAAAA7 --part1_e.26cd4d1a.2adac486_boundary--
