If you're looking for a quicker and easier approach, Aeromotive has you covered with its on-rail regulator. While the stock regulator works fine for mild applications, it looks rather humble compared to the adjustable unit from Aeromotive (top). Aeromotive recently changed the design of the LT1 regulator due to the corrosive nature of fuel additive changes in 2002. This change resulted in a more robust but larger regulator which requires some minor fabrication in its installation. In response to customer feedback, Aeromotive is now shipping the new regulator with an installation kit and updated instructions.
