JomGorg Fuel Pressure Regulator Vacuum Line Tube — 1999–2005 4.8/5.3/6.0, Oil‑Resistant with Snap Clip

JomGorg's fuel pressure regulator vacuum line tube is a direct-replacement vacuum hose assembly engineered to restore correct fuel pressure control on compatible GM V8/V6 engines from 1999–2005.

This replacement vacuum line tube fits many Chevrolet, GMC, Cadillac, Buick, Hummer and Isuzu models and replaces OE/service part numbers such as 17113556, 19236428 and 2173299. Built from oil-resistant material and supplied with the snap-clip ring, the part is intended to reconnect the regulator's vacuum port securely and help the fuel system behave as designed after the original tube becomes cracked, hardened, or lost.

How does this part match original equipment numbers?

The JomGorg tube is manufactured to replace multiple OE and aftermarket reference numbers, so it can be used where the original vacuum hose or regulator link has failed. Cross-reference the listed part numbers against your service manual or parts catalog to confirm match.

• Replaces: 17113556, 19236428, 2173299 and related service codes
• Also compatible with aftermarket references: FP10021, PR203, PR217, PR155, 217-3073
• Supplied with clip snap ring for secure vacuum port retention

What materials and durability features does this tube offer?

The tube is produced from oil-resistant elastomer designed to withstand contact with fuel vapors and engine bay contaminants, extending service life versus aged factory rubber. Proper sealing and flexibility help maintain vacuum integrity for accurate regulator response.

• Oil-resistant material resists softening and swelling from fuel exposure
• Flexible construction for routing in tight engine compartments
• Includes snap ring/clip to prevent unintended disconnection

Can I install this myself and what should I check during installation?

Many do-it-yourselfers can install the vacuum line with basic hand tools: remove the old tube, inspect the regulator and fittings, fit the new tube, and secure the supplied clip. If uncertain about fitment, provide your VIN to the seller or consult a trusted technician.

• Inspect mating ports for debris or damage before connecting
• Use the included snap clip to lock the tube onto the regulator fitting
• Start the engine and check for stable idle and no vacuum leaks after installation

Who is this for: This JomGorg vacuum line tube is for owners or technicians working on late‑1990s to early‑2000s GM trucks and SUVs with 4.8L, 5.3L or 6.0L engines who need a reliable replacement part that matches common OE numbers. It suits vehicles where the factory vacuum hose has become brittle, cracked or missing, and for anyone preferring to replace the regulator feed with an oil‑resistant aftermarket option. If you have doubts about fitment, provide your VIN when ordering and reach out to the seller for confirmation prior to installation.
