A lot of gearheads learned how to set their fuel pressure as a teenager watching their dad tinkering with his hot rod in the garage, and in many cases, that’s where the lesson began and ended. For a lot of cars, that works just fine. However, as horsepower levels increase, more fuel is needed and the components required to match that increased demand become more precise and intricate, and that’s where an article like this one can help ensure your fuel system is performing at its best.

The How-To, posted last month by Fuelab’s Jon Light, walks you through the process of setting your fuel pressure using a blocking-style regulator correctly to avoid the dreaded phenomenon of pressure creep, which leads to inconsistent fuel pressure readings during the adjustment process and a host of headaches while trying to achieve the ideal fuel pressure for your system. After an in-depth explanation of pressure creep itself, Light explains the correct procedure for setting your pressure to ensure you get accurate and consistent fuel delivery, ensuring happy motoring while eliminating a potential threat to your engine’s health.

Many of our astute readers already know that one solution to this problem is simply setting the pressure at the regulator while the engine is idling — and you’d be correct. However, in some cases, that may not be an option, and that’s where the true value of this Hot-To shines, as Light offers advice on how to properly set your regulator using bleed returns to simulate fuel flowing through the system while you lock down the correct pressure setting. Check out the full article to read through the steps, which are laid out in simple, concise terms to ensure even the novice fuel tuners out there are still able to follow and understand the process!
