Enderle Fuel Pump: What You Need to Know Before Buying One for Your Race Car
If you're building a serious race car—whether it's for drag racing, sprint car competition, or blown methanol applications—an Enderle fuel pump is one of the most reliable and time-tested choices you can make. Enderle has been setting records and winning championships for over fifty years, and their spur gear and hex-driven fuel pumps are built to handle the toughest conditions, from gasoline and alcohol to nitromethane. The bottom line: choose an Enderle pump if you need consistent fuel delivery at high pressure, a fully rebuildable design, and the flexibility to run standard or reverse rotation.
What Makes Enderle Fuel Pumps Different?
Enderle fuel pumps stand out because they use a spur gear design rather than a vane-type pump. Gear pumps are known for better longevity and consistency compared to vane pumps, which is why they are the go-to choice for racers who cannot afford a fuel delivery failure.
The pump starts with a steel housing that has a special black coating for wear resistance. It uses a steel .375" male hex drive with a slip collar, which allows you to rotate the pump 360 degrees to position the inlet and outlet exactly where you need them. This is a huge advantage when space is tight in an engine bay.
Another key feature: you can switch between standard and reverse rotation simply by flipping the drive gear on the pump housing. No need to buy a different pump if you change your engine setup.
Available Enderle Fuel Pump Models
Enderle offers several models to match different horsepower levels and fuel requirements. Here are the most common options:
1. SG1 Spur Gear Fuel Pump – 5.7 GPM
This is the workhorse model. It flows 5.7 gallons per minute (GPM) , has a 3-bolt mounting pattern, and uses -8ORB inlet and outlet fittings. It weighs about two pounds and measures 3.50 inches end to end. All aluminum parts are hard anodized for corrosion resistance. It's compatible with gasoline, alcohol, and nitromethane.
2. SG1-480 – Hex Driven Inline Pump – 4 GPH
This pump flows 4 gallons per hour (GPH) and is designed for inline mounting. It has 8 AN female inlet and outlet ports, an aluminum body with black paint, and is suitable for methanol use. It's a good choice for smaller engines or applications where you don't need maximum flow.
3. SG1-750 – Hex Driven Inline Pump – 7 GPH
For higher horsepower builds, the 7 GPH version steps up the flow. It also uses 8 AN female fittings and is compatible with ethanol, gasoline, and methanol. It weighs about 1.4 kg (roughly 3 pounds) and is built to handle the demands of competitive racing.
4. 110 Fuel Injection Pump – 13.0 GPH
If you're running a serious blown application, the 110 series pump delivers 13.0 GPH. It has a larger 12 AN female O-ring inlet and an 8 AN female O-ring outlet. It's designed for alcohol, E85, and gasoline. This is a step up for high-horsepower, forced-induction engines.
5. 1100 Fuel Pump – 17.2 GPH
For the biggest builds, the 1100 mechanical fuel pump flows 17.2 GPH. It also uses a 12 AN inlet and 8 AN outlet. This pump is commonly used in blown methanol applications where fuel demand is massive. Flow figures are measured at 4000 RPM shaft speed at 100 PSI.
How to Choose the Right Enderle Pump
Selecting the right pump comes down to three factors:
1. Horsepower and fuel demand. The more power you make, the more fuel you need. A 4 GPH pump might work for a moderate street/strip car, but a blown alcohol engine at 1000+ horsepower will need a 13 or 17 GPH unit.
2. Fuel type. All Enderle pumps work with gasoline and alcohol. Some are specifically rated for methanol and nitromethane. Make sure the pump you choose is compatible with your fuel.
3. Mounting and rotation. Enderle pumps can be cam-driven or belt-driven. The hex drive design gives you flexibility. You can also run them at half engine RPM, which is the standard practice.
Rebuildability and Maintenance
One of the best things about Enderle pumps is that they are fully rebuildable. You can replace O-rings, seals, bearings, and hard parts. This means you don't have to throw away the whole pump when something wears out. It saves you money in the long run and keeps your pump performing like new.
Where to Find Enderle Fuel Pumps
Enderle pumps are available through specialty racing parts retailers. Prices vary by model and flow rate. For example, the SG1-480 4 GPH pump is listed around $1,062.97, while the larger 110 series pump can be found for around $1,116.96. Always check availability, as some models may be out of stock at certain retailers.
