Gen V LT Heater Fittings for Corvette Water Pump LT1 LT4 - 5/8 (Feed) / 3/4” Hose Barb / 90 Degree

Gen V LT Corvette water pumps have quick-connect fittings for the heater ports. A typical hose won’t clamp to these ports properly. Lucky for you, we have a solution! 
Choose from straight or 90 degree angle, AND 5/8 or 3/4 barb to match your heater core. We also offer 12AN if you want to get real fancy with your heater plumbing. 
The 5/8” port is the “feed” to the heater core, while the larger 3/4” port is the return.
