engine did not cause it to go out...it is the way the strainer and screen on bottom of assembly is made...they revised it on the cougars after the contour phased out because the screen and strainer would catch debris and clog up causing it to strain the pump...stations around here dont really filter their fuel well and there tanks get rubbish in them and it gets passed along to the consumer. sorry I consider this a rebuild that is why I posted it here...probably an unwise choice now that I look.
