One part of project car building that often gets quickly glossed over is the fluid systems. That's partially because in most cases it's not all that glamorous or photogenic, but each part of the pipeline is absolutely critical to making a car run. Fuel, oil, water—you're not going anywhere without all three of these flowing.

When it comes to plumbing fluid systems for high-end performance, though, things get a bit more interesting. The harder you push a car, the more reliable and effective each of those systems must be or the fun will be over fast. In many cases some factory original parts will suffice, but on a project like the Max Effort 1967 Cougar, which will see both heated track use and rush-hour traffic, we have to start from scratch. That's good news for all you pondering the job of upgrading your own project because we're planning to walk you through the right way to handle each of these for both safety and performance.

We have to tackle all three major fluid systems in the Cougar, but we're going to start with the fuel system, and a bit of a primer on building your own -AN fuel lines. Rather than standard stainless braided line, we chose Earl's Plumbing Pro-Lite 350 hose and Ano-Tuff fittings. The Pro-Lite hose is very flexible and saves a huge amount of weight versus stainless, plus it's actually much easier to assemble. That not only leads to less frustration during assembly, but also a clean-looking final installation. Yes, looks do count, so prepare to spend a great deal of time just staring, pondering, and planning before cutting the first hose.

A slick-looking plumbing system is a hallmark of a well-built car for two reasons. First and most obvious is that it creates a pleasant and non-cluttered look that won't distract from the rest of the car. Second, that same clean and uncluttered layout makes a system intuitive and easy to trace and service. Good thing Yannick Sire of Sire Custom Performance is a huge stickler for combining function with form on his plumbing systems for anything from street to race cars. With his years of experience, he's going to show us the right way to start with a couple rolls of hose and a pile of fittings and craft a high-end, race-bred fuel system from scratch.
