Well - our's leaked oil after 5 months. Edelbrock tech sent me the repair parts - not a big deal. Pump worked for about 4 weeks more then quit. It's in a box on the bench, haven't torn into it to see why - been too busy. Not a ringing recommendation. I put the old stocker back on it and we've been racing that for months now. About a 240HP 302. I'd use 3/8 line anyway - most of the performance pumps use that size fitting. Depending on the car, your feed from the tank may only be 5/16".
