There is a fuel filter/water strainer on 2001 and up HPDI just to the side of the fly wheel. It has 2 Oetiker clamps on it. I priced them on the Internet and at boat shops and they want $13 -$15 a piece for them. I found a company on the web that has USA made Oetiker clamps for $1.11 each plus shipping. Their name is Bel-Metric Inc. I ordered what I thought were the correct ones but they were way to small, called them and have the new ones coming and the wrong ones going back hassle free. Call them at 978-649-6201, use option 2 to get the correct ones. Happy fishing
