Product Details

The Edelbrock 3581 in-tank fuel pump is specifically engineered for multi-point fuel injection (MPFI) conversion applications on 1987-1995 Chevy and GMC trucks originally equipped with throttle body injection (TBI) and a single fuel tank. This high-pressure fuel pump replaces the factory low-pressure in-tank pump to meet the demanding fuel delivery requirements of port fuel injection systems.

Key Features:

  • Direct replacement for OE in-tank fuel pump on TBI-equipped trucks
  • High-pressure output designed for multi-point fuel injection systems
  • Compatible with single tank configurations only
  • Engineered for 1987-1995 Chevrolet and GMC truck applications
  • Essential component for TBI to MPFI conversion projects

When converting your TBI Chevy or GMC truck to a modern multi-point fuel injection system, upgrading to a high-pressure fuel pump is critical for proper engine performance and reliability. The Edelbrock 3581 provides the necessary fuel pressure and flow rate to support port fuel injection, making it an ideal choice for engine swaps, fuel system upgrades, and performance conversions.
