PFS Stage Cheap DIY Fuel Pump Upgrade Kit (plus limited Pre-Built units available)

Need more fueling headroom but don’t want to drop big money on a full upgrade? The Stage Cheap DIY kit is exactly what it sounds like — an affordable, effective way to boost your low-pressure fuel pump performance without adding wiring, controllers, or complexity.

This kit repurposes high-quality OEM-based components into a high-flow solution for the A90/A91 Toyota Supra and most B58 powered BMW G-Series platforms (excluding M3/M4, X3M/X4M, and X3M40i).

Key Features:

✅ ~50% more flow than a stock LPFP
✅ Once assembled, kit is 100% plug-and-play
✅ No additional wiring or external controllers required
✅ Retains full factory fit and function
✅ Ideal for pump gas or E85 builds
✅ Built from OEM-quality components
✅ A perfect entry-level fueling upgrade

Either version can be bundled with our budget-friendly toolkit — everything you need to modify your LPFP to Stage Cheap, no extra tools or guesswork required.

Note: This is a DIY kit. You’ll be upgrading your own LPFP using our provided instructions (we'll email them to you in .pdf format). It’s a fairly simple job, no soldering or complex work required but if you're super ham-fisted, you can pooch it. If you're not confident with pump assembly work, professional assembly is recommended (which, we can do for you if you like).
