Butler Performance Inc. » Rob Mc Performance
Butler Performance focuses purely on traditional engine platforms, delivering absolute precision to racers and street performance enthusiasts who refuse to settle for generic modern swaps.
The Fuel Starvation Problem
High-horsepower builds require a serious amount of fuel, but stock fuel systems often restrict flow. When you push your classic machine on the track or the street, inadequate fuel delivery leads to lean conditions, severe power drop, vapor lock, and catastrophic engine damage. Factory sending units and standard mechanical pumps simply cannot keep up with the demands of an upgraded engine block or high-flow Pontiac cylinder heads.
The Ultimate Fuel System Solution
To solve these common fuel delivery restrictions, we stock high-grade Rob Mc Performance Pontiac parts designed to handle extreme fuel demands. Our curated product line includes high-volume six-valve mechanical fuel pumps, billet bypass regulators, dead-head fuel pressure regulators, and heavy-duty fuel tank sending units. These components are specifically engineered to fit classic muscle car chassis, ensuring your fuel delivery system matches the rigorous output of your engine.
Benefits of Upgrading Your Fuel Delivery
Upgrading to these performance components eliminates the classic vulnerabilities of vintage fuel routing. You get consistent fuel pressure under full throttle, reduced restriction, protection against vapor lock, and full compatibility with modern high-octane fuels. These components allow your machine to achieve its true horsepower potential while maintaining long-term reliability during heavy acceleration.

Frequently Asked Questions
Can I run a high-volume mechanical pump with my factory fuel lines?
No, factory fuel lines are too small and act as a tight bottleneck. We recommend using a minimum line size of three-eighths of an inch for applications up to 450 horsepower and a full half-inch line for anything pushing past that mark.
Do these high-volume mechanical fuel pumps require an external regulator?
The 130 gallon-per-hour model operates safely at seven pounds per square inch and runs fine without a regulator on carbureted setups. However, the larger 176 gallon-per-hour pump delivers massive volume and requires a specialized bypass or dead-head regulator to prevent flooding your carburetor.
How does the rotatable valve body assist with tight engine bays?
Classic engine bays often suffer from severe space constraints near the timing cover and chassis crossmembers. The unique design allows you to loosen the body and spin the inlet and outlet ports to any angle, providing clean routing for your plumbing without hitting the block.
Are these sending units compatible with factory fuel gauges?
Yes, these custom sending units are engineered with the correct electrical ohm resistance to communicate perfectly with your original dashboard instruments. You get modern high-flow capabilities without losing your classic factory dash appearance.
