FAQ
Will this kit support my tuned or lightly modded L5P?The 140 GPH No Drop kit is sized for stock to roughly 500 HP L5P builds. If you plan larger injectors or aggressive tuning, step up to the 220 GPH or 240 GPH systems linked above.
Do I need to drop the tank to install it?
No. The included SK5501 return-style sump allows a clean, single-hole install without removing the tank, which cuts time and hassle dramatically.
What filtration does it provide compared to OEM?
FASS filters to 2-micron absolute and removes air/vapor and >99% of water, which is significantly better than stock. This helps extend injector and pump life.
Is a heater kit available for cold climates?
Yes. Electric fuel heater kits are available for the Titanium Signature Series if you operate regularly in sub-freezing temps.
