Where to buy hoses

You can buy the rubber caps in the Help section at auto parts. But, I just carry for emergency use. They don't seem rugged. My 2002 3.8L factory plumbing had one capping an unused port on the rear of the water pump housing. It leaked, and at first I ASSumed it was the water pump. I replaced w/ a short section of 5/8" silicone heater hose (ebay) w/ a copper cap inside. You might just loop it. Silicone is more flexible so the loop can be shorter. It also will last forever. For bling, it comes in blue, or black for stealth.
