Cruiser Fuel System

Frequently Asked Questions

• How do I choose a fuel controller for a cruiser with intake/exhaust mods?

  Pick a unit that matches your engine type and lets you adjust AFR to your octane needs, preventing knock and smoothing throttle. Start with a map suited to your mods, then fine-tune after a short test ride.
• Carbureted vs. fuel-injected cruiser—what pump and filter setup should I use?

  Carb setups favor low-pressure pumps with a coarser pre-pump filter; EFI needs precise pumps and finer post-pump filtration. Confirm materials are compatible with unleaded fuel and resistant to ethanol.
• How can I protect my cruiser’s fuel system from ethanol-related issues and storage?

  Choose ethanol-resistant lines, seals, and filters, and pair fuel with a stabilizer or non-alcohol additive for longer storage. Whenever possible, use ethanol-free unleaded and replace filters if fuel sits.
• What fuel lines and fittings are best for a leak-free cruiser install?

  Use gasoline-rated, ethanol-safe lines and verify thread/fitting standards (Metric, JIC/AN, NPTF, BSP) across components. Route away from heat and abrasion, and secure with quality clamps for long-term reliability.
• Does octane rating affect which fuel products I should buy for my cruiser?

  Yes—follow your manual’s octane and select controllers that can richen AFR for higher-compression or tuned engines to resist detonation. After refueling, listen for pinging and adjust tuning if needed.
