New heater hose for Datsun 510, 68-73. This is the longer hose that goes from the front of the engine and through the firewall. This hose has an overall length of 20". Choose from OEM or aftermarket.
*The aftermarket hose is a similar hose (universal) but not a perfect fit, will require cutting the length down. This hose is just an option we have if the OEM becomes not available or just a less expensive option.
