Hey 4onthefloor, thanks for all the info. I don't know why, but I was assuming that the extra outlets were on the maninfold side of the motor. The thermo housing looks like it has the extra heater hose outlet on the topside of the thermostat housing. Is this the bypass setup to the pump you were refering to? How would you hook it up "correctly" to warm an intake? Also, I found a new 261 pump at the local Napa store for $55. I'm tickled pink that I soon will be able to heat my intake using hoses that look like they should be there!
