Dorman Fuel Pump Cam Follower 926-441 — Direct-Fit OE-Equivalent for GM (2007–2021) Restores Fuel Pressure

The Dorman 926-441 fuel pump cam follower is an OE-equivalent replacement part designed to restore proper fuel pump pressure and reliable operation in compatible GM vehicles.

If your vehicle is showing low fuel pressure symptoms — rough idling, intermittent stalling, or an illuminated engine warning light — worn cam followers can be the culprit. The Dorman 926-441 cam follower replaces the original equipment piece that actuates the high-pressure fuel pump, helping the pump maintain correct pressure and consistent fuel delivery. This aftermarket unit is engineered for a direct fit and long service life for a wide range of Buick, Cadillac, Chevrolet, GMC, Pontiac and Saturn models from model years approximately 2007–2021. Always confirm fitment by entering your vehicle's exact make, model and trim in the garage tool before ordering.

How will the Dorman 926-441 address low fuel pressure and drivability problems?

Replacing a worn cam follower restores accurate mechanical actuation of the fuel pump, which can improve fuel pressure stability and smooth engine operation. It addresses symptoms caused by reduced pump stroke or inconsistent contact between the cam and follower.

• Restores correct pump actuation for steady fuel pressure
• Reduces surging, rough idle and hesitation related to fuel delivery
• Helps clear fuel-related engine fault codes when the mechanical cause is fixed

Will this part fit my vehicle and how do I confirm compatibility?

The 926-441 is designed to be a direct replacement for specific GM engines across many model years; fitment varies by vehicle and trim. Use the store’s garage tool to input your exact year, make and trim to verify compatibility before purchase.

• Compatible with listed Buick, Cadillac, Chevrolet, GMC, Pontiac and Saturn models (see product details)

How difficult is installation and what should I prepare for?

Installation complexity depends on vehicle access to the fuel pump cam follower — some engines require partial disassembly to reach the part. If you have moderate mechanical experience and basic tools, this is typically a job for a home mechanic; professional installation is recommended if you’re unsure.

• Requires basic hand tools and, in some applications, removal of ancillary components
• Follow vehicle service manual for torque specs and reassembly sequence
• Shop installation is advised if access is limited or specialty tools are needed
