Goopool Fuel Pressure Regulator Hose for 3.8L GM V6 — Direct-Fit 24506640, Oil-Resistant Replacement

Goopool 24506640 fuel pressure regulator vacuum/vapor purge harness is a direct-fit replacement hose designed for 3.8L Buick, Pontiac and Oldsmobile models from 1998–2005.

This replacement harness restores the vacuum and vapor routing for the fuel pressure regulator on compatible GM 3.8L engines. Built from oil-resistant material, the Goopool hose is manufactured to match the original geometry and connection points so it installs quickly and helps eliminate leaks related to cracked or brittle factory hoses. It replaces part number 24506640 and is engineered to fit a range of Buick, Pontiac and Oldsmobile vehicles listed below.

Which vehicles will this Goopool hose fit?

The harness is intended for GM 3.8L V6 applications from the late 1990s and early 2000s. It covers multiple models that used the same fuel pressure regulator vacuum routing and original part number 24506640.

• Buick Century and Regal (1998) with 3.8L engines
• Pontiac Grand Prix (1998) and Bonneville (2000–2005) 3.8L
• Oldsmobile Intrigue (1998 2nd design and 1999) 3.8L
• Buick Park Avenue (1998–2005) and LeSabre (2000–2005) 3.8L

How straightforward is installation on these vehicles?

Installation is intended to be a straightforward swap for the factory hose: the Goopool part is molded to match OE connection points so minimal adjustment is required. Typical installs are completed with basic hand tools and about 20–45 minutes of time, depending on access and vehicle layout.

• Direct-fit dimensions to replace part 24506640 without trimming
• Oil-resistant material reduces degradation and future leaks
• Requires simple clamps or factory fittings already present
• No special tools or programming needed

What performance and durability differences can I expect?

The hose uses oil-resistant elastomer designed to resist fuel vapors, heat and oil exposure that degrade older hoses. While not an OEM-branded component, the construction aims to restore proper vacuum control and prevent vapor leaks that lead to rough idle or diminished regulator response.

• Resistant to oil and common automotive fluids for longer life
• Restores correct vacuum routing for the fuel pressure regulator
• Helps prevent vacuum leaks that may affect idle stability
• Sold as a single replacement harness matching OEM fitment

What should I check before ordering and after installation?

Verify your vehicle year, engine (3.8L) and whether the factory part number matches 24506640 to ensure compatibility. After fitting, inspect clamps, routing and perform a visual leak check with the engine running to confirm sealing and proper operation.

• Confirm original part number 24506640 on your vehicle
• Check hose routing matches factory path and avoids heat sources
• Tighten any clamps to manufacturer torque recommendations
• Run engine and inspect for vacuum or vapor leaks visually

Who is this for: This Goopool replacement harness is for DIY mechanics, independent shops and vehicle owners driving 1998–2005 Buick, Pontiac or Oldsmobile models with the 3.8L V6 who need a cost-effective direct-fit replacement for part 24506640. It suits anyone restoring factory vacuum/vapor integrity, mitigating leaks from aging rubber lines, or completing routine fuel-system maintenance without sourcing an OEM hose.
