coolant hoses
 

i got a 92 12 valve and i wondering where i can find new coolant lines and the oil return line i dont know if i can just use regular rubber hose or if it has to be specific

NAPA should have cut to fit radiator hoses and I think if you ask they'll cut off heater core hoses to any length. The lower hose might try to kink if its too long and it doesn't have the support spring thingy inside. Napa should also have the oil return from the turbo, if not, maybe Cummins or some Holset retailer?
