Fuel Pump Relay Replacement: Essential for all Mitsubishi Lancer Evo X and Ralliart model years 2008 - 2015. We recommend replacement every 2-3 years as this relay sees a lot of cycles during normal driving, and when it fails it causes your fuel pump to run in low voltage mode only. This leads to an extreme lean condition under boost which can result in severe engine damage.
FPR Hose Replacement: This is a very common failure point on the 4B11T as well. The factory uses no clamps on the Fuel Pressure Regulator reference hose which when combined with a brittle, dry-rotted hose, can lead to the hose coming off. This results in severely lean fueling under boost and a poor run condition due to the resulting vacuum leak. We replace the failure-prone factory hose with a snugly fit 3 mm silicone hose and two appropriately sized zip ties for a foolproof yet simple solution.
So to find out that FPR hose was completely worn out and disconnected. Thanks for the product!!!
