Precision Raceworks G-Series High Performance Fuel Pump Kits – Stage 2 & 2.5

Designed for E85 | Hybrid Bucket/Bucketless | High-Flow | Plug & Play

🔥 NOTE: STAGE 2.5 IS CURRENTLY ON BACKORDER!

The Precision Raceworks G-Series High Performance Primary Fuel Pump Kits are engineered for enthusiasts who demand maximum fueling capability with full E85 compatibility. These kits are ideal for setups using a single fuel line to power both the high-pressure fuel pump (HPFP) and port injection (PI).

⚠️ Caution – Don't Risk Your Injectors!

Unlike other brands, Precision Raceworks kits include proper post-pump filtration. Competing kits that bypass this with a Y-fitting (after the OEM filter) can allow debris to reach your HPFP and direct injectors — leading to premature failure. We protect your system with a 10-micron inline filter, designed and built in the USA.
