Need help please. I have a 2005 Chaparral with twin Volvo 4.3 Gxi e motors with a fuel pump problem. One motor is running fine the other... the fuel pump was getting hot and whinning. I replaced the $650.00 fuel pump and it's still getting hot. It doesn't whine but I don't want to run it and burn up the new fuel pump. I took out the anti-syphone valve it looks ok, I'm going to replace it anyway. The fuel filter was fine with no water. Any ideas. Thanks.
