Spool Stage 3 LPFP DIY Kit | Toyota Supra B58 Gen2

The Spool Performance Stage 3 LPFP DIY Kit is a low-pressure fuel pump upgrade for the Toyota Supra A90/A91 (B58 Gen2) platform. This solution is aimed at enthusiasts who want a cost-effective DIY solution to remove fuel delivery limitations.

The stock low-pressure fuel pump often becomes a bottleneck with high power and especially with E85 use. This Stage 3 DIY kit adds a secondary, boost-controlled pump to the system, significantly increasing fuel flow capacity.

• DIY solution (self-assembly)
• Significantly more affordable option compared to plug & play solutions
• Dual pump system
• Secondary pump activates according to boost pressure
• Almost the same flow capacity as pre-assembled Stage 3 kits
• E85 compatible

Operating Principle

• Stock pump operates normally under light load
• Auxiliary pump activates as boost increases
• Increases fuel delivery at high power levels
• Removes low-pressure side limitations

Why is an upgrade necessary?

The stock LPFP on the B58 Gen2 platform is insufficient for high power levels:

• E85 requires significantly greater fuel flow
• Larger turbos increase consumption
• HPFP needs a consistent and sufficient supply to operate correctly

Stage 3 LPFP DIY:

• Removes the low-pressure side bottleneck
• Enables high power levels
• Offers a cost-effective solution

Package Contents

• Bosch fuel pump
• Billet aluminum pump bracket
• E85-compatible corrugated T-hose
• 4x hose clamps
• Activation wiring harness
• Boost-controlled switch
• Boost reference adapter
• Installation hardware kit
