Tips for taking the cap off:


Note: The built-in anti-slosh foam inside the fuel cell gas tank helps improve fuel delivery, stabilize fuel flow, and reduce the risk of flashback explosions. For optimal performance and safety, inspect the foam regularly and replace it if signs of wear or deterioration appear.
This adjustable fuel pressure regulator is engineered for most EFI fuel cell systems and supports both gasoline and E85 fuels. Designed for performance and reliability, it ensures precise fuel delivery across a wide range of applications. For a secure, leak-free installation, always apply thread sealant tape to the NPT pressure gauge port.

Engineered for precision fuel filtration, this fuel cell filter ensures clean, consistent fuel delivery by capturing fine debris and contaminants before they reach your injectors or carburetor. Ideal for EFI fuel cell systems and performance builds, it offers both protection and longevity.
