Goopool fuel pressure regulator vacuum/purge hose for 3.8L Buick 24506640 replacement — oil-resistant, direct-fit

Goopool's 24506640-compatible fuel pressure regulator vacuum/purge hose is a direct-fit replacement designed to restore proper fuel-canister and regulator connections on select 3.8L Buick, Oldsmobile and Pontiac models.

This replacement harness addresses the vacuum and vapor purge plumbing that links the fuel pressure regulator and charcoal canister. Engine bay hoses can crack, harden, or leak over time, causing rough idle, increased evaporative emissions, or fuel system performance issues. The Goopool unit is molded from oil-resistant material and sized to match factory routing so you can swap it in without major modifications.

How does this replacement hose affect engine performance?

Replacing a failing vacuum or purge harness eliminates unintended leaks between the regulator and evap canister, helping the fuel system maintain correct pressure and reducing vapor loss. While not a performance part, a sound connection supports steady idling and consistent fuel delivery.

• Stops vacuum leaks that can cause rough idle or stalling
• Maintains designed fuel pressure behavior at the regulator
• Reduces evaporative emissions by restoring purge plumbing
• Helps prevent check-engine codes related to EVAP or vacuum leaks

Is this Goopool harness an original equipment part?

This is an aftermarket replacement manufactured to match the form and function of the OEM 24506640 hose assembly. It is not a factory-produced GM part, but it is designed as a direct swap for vehicles listed in the compatibility section.

• Replaces OEM part number 24506640 (confirm fitment first)
• Aftermarket manufacturing with factory-style dimensions
• Sold as a direct replacement, not branded General Motors equipment
• Customer support offered for quality or fitment concerns

How difficult is installation and what should I expect?

Installation is straightforward for a DIYer familiar with basic engine-bay work. The harness uses factory connection points and clamps; removal of the old cracked hose and transfer of any retaining clips may be required. Plan for a short service window and standard hand tools.

• Direct-fit design keeps installation time short
• No special tools needed beyond pliers and screwdrivers
• Inspect and replace clamps if corroded before final assembly
• Verify secure seating at regulator, canister, and vacuum ports

Who this is for: This Goopool replacement harness is aimed at owners or mechanics restoring proper fuel-regulator and EVAP plumbing on late‑1990s to early‑2000s GM cars with the 3.8L V6. If you own a compatible Buick, Oldsmobile, or Pontiac and are troubleshooting vacuum leaks, EVAP codes, or degraded hoses, this unit offers a cost-effective, oil-resistant aftermarket option that mirrors the original routing and connections.
