The two coolant lines hooked up to my EGR spacer seem to be about 1/4" heater hose, but I can't find that anywhere (my rear one cracked and left a nice white residue over the entire rear of my engine)! Do I have the size mixed up, or will 1/4" fuel line suffice? Seems questionable given the temperature...
Also, for the lines running to the heater core pipes on the firewall, are they both 1/2"? Looking from the front of the engine toward the rear, does the left one attach to the top hard coolant line? Just trying to get my facts straight before I replace the darn things. Thanks!
