hi folks

is there anyone using a pump with the cooling coils. i just got one from a 73 f700 (is there such a beast?) i removed the coils from the can for derusting and a clean up and found the coils were wearing a groove into the can! i suppose its the coils vibrating.

has anyone had a leak due to coils wearing thro? should i insert a teflon strip between coils and can? it probably wouldn't wear thro in my lifetime. looks like a still on the front of the motor.any thoughts please
