I need some help. Ever since I changed my mechanical fuel pump to an electric one, my engine runs cold (130' to 140' degrees) Today I put in a 195' degree thrermostat to see if that would do the trick, no luck. I know the mechanical pump was creating a ton of heat, due to the vapor lock conditions I was experiencing. When I changed that out to an electrical fuel pump my vapor lock problems went away, but now the motor runs too cool. Could it be the radiator cap, the heater only pumps out luke-warm air. I am taking the temp reading off the gauge and off an infrared temp gun, they are the same. I guess I could put some cardboard in front of the grill to limit the amount of cold air thats drawn in. What do you think, thanks for any replies. O'77
