Thread: Water pump/heater hose question

Tweet

Hello everybody,

I have a water pump heater hose port question. Ive searched the edelbrock web site, and this forum but didnt find info for my question. Basically Iam not sure which heater hose port to use, on the water pump, for the return line from the heater core.

in this side view pic of my water pump, there are 2 heater hose ports on the water pump. can anybody tell me which port is the suction, or the return port from the heater core. Are they both return ports or suction ports????.

Currently i have the heater hose attached to the top port. but i started to think about it, and wondered why there are 2 ports instead of one and now im confused......any help would be appreciated

oh ya.....the water pump is a new, standard direction, short neck edelbrock w.p, the motor is a 350 SBC
