Edelbrock Banjo Bolt and Fitting
Edelbrock Banjo Bolt & Fitting: Precision Fuel Connections for Performance Carburetors
When building or restoring a performance engine around a classic carburetor, every connection in the fuel system matters. Edelbrock — one of the most recognized names in American performance parts — extends that same engineering discipline to the small but critical details, including the banjo bolt and fitting hardware that keeps fuel flowing reliably to the carburetor inlet.
What Is a Banjo Bolt and Fitting?
A banjo fitting is a specialized plumbing connector used in fuel and hydraulic systems. The banjo bolt is a threaded cylindrical bolt that passes through the banjo body and is secured in place with washers, featuring a hole through its center that allows fluid to pass through. The banjo body is a hollow, cylindrical piece designed to fit snugly with the banjo bolt and washers to create a tight seal. In a carburetor application, this assembly forms the connection between the incoming fuel line and the carburetor's inlet port — a joint that must remain leak-free under sustained heat and vibration.
Edelbrock Part #8089 – Engineered for a Perfect Fit
Edelbrock's primary offering in this category is the Banjo Bolt and Fitting #8089, purpose-built to integrate seamlessly with their own carburetor lineup. The Edelbrock Banjo Fitting #8089 is designed for Edelbrock Square-Bore & Carter AFB Carburetors. This is not a generic adapter — it is a direct-fit component developed alongside the very carburetors it serves.
The #8089 is a 90° banjo fuel fitting with a 3/8" inlet and 5/8"-20 thread, and it fits Performer & Thunder Series carbs. The 90-degree angle is a practical design choice: the 90° banjo fitting solves clearance issues where the hood won't close because an air filter sits too high , making it an important solution for engine bay packaging in street rods, muscle cars, and project builds.
Fitting End A measures 5/8"-20 and Fitting End B is 3/8", with a hex wrench interface designed for 3/8" fuel line. This banjo fitting from Edelbrock features an inlet fitting that is a must-have accessory when installing or tuning your Edelbrock carburetor.
Why Edelbrock for Banjo Fittings?
Choosing an OEM-matched fitting from Edelbrock rather than a generic substitute carries real advantages. Because the #8089 is engineered specifically for Edelbrock Square-Bore and Carter AFB applications, thread engagement and sealing geometry are optimized for those exact inlet bosses. The unique threading feature sets it apart from competitors, and it has proven to be durable and reliable, with no leaks reported.
Edelbrock's decades of experience developing integrated carburetor systems — from manifolds to fuel bowls to inlet hardware — means this fitting is designed as part of a cohesive system, not an afterthought. For builders who have already invested in an Edelbrock Performer or Thunder Series carburetor, using the matching Edelbrock banjo fitting ensures the entire fuel circuit performs as intended.
A Small Part That Makes a Big Difference
In performance builds, fuel system integrity is non-negotiable. A leaking or mismatched banjo fitting can cause fuel seepage, inconsistent delivery, or serious safety hazards. Edelbrock's attention to fit and finish in even their smallest hardware reflects the brand's commitment to building complete, reliable performance systems.
