⚠️ Usage Notes

All kits include a standard Walbro filter assembly. If you routinely drive under 1/8 tank or track your car on long right-hand corners with less than ½ tank, we recommend upgrading to the PFS bucketed LPFP. The bucket helps maintain consistent fuel pickup under aggressive driving conditions.

Also, PFS only uses modern fuel tubes (not rubber hose), which are fully compatible with today's ethanol-enriched fuels and chemical additives like toluene, xylene, and MTBE. Rubber degrades rapidly under these conditions and can lead to vapor leaks, swelling, bursting, or system failure. Our assemblies are built for modern fuel system demands — no compromises.
