Buying Guide: What to Look For in an Adjustable Electric Fuel Pump
When I’m working on my 55 Chevy, I know that the heart of its performance often comes down to the fuel system. Swapping out the old mechanical pump for an adjustable electric fuel pump can be a game-changer, especially if you’ve made any engine upgrades. But with so many options out there, it can be tricky to pick the right one. I’ve learned a few key things to look for that make the decision a whole lot easier.
First, consider the fuel pressure and flow rate your engine actually needs. A stock 265 or 283 might be perfectly happy with a pump that delivers 4-7 PSI, but if you’ve dropped in a built 350 or a modern LS engine, your needs are different. Carbureted engines generally need lower pressure (typically 4.5-7 PSI), while fuel injection systems demand much higher pressure, sometimes up to 60 PSI or more. Getting a pump that can be dialed in to your specific pressure is crucial for performance and engine health. Too much pressure can overwhelm your carburetor’s needle and seat, causing it to run rich, while too little will lead to fuel starvation.
Next, think about the pump type. For a street-driven 55 Chevy, a rotary vane style pump is often a great choice. They’re generally quieter and more reliable for daily use. If you’re building a high-horsepower beast or a dedicated race car, you might look into a brushless pump for ultimate durability and flow. Also, pay close attention to the installation kit. A good kit will include everything you need—the pump itself, a pre-wired harness with a relay, a filter, and all the necessary fittings and hardware. This saves a ton of time and frustration hunting down individual parts.
Finally, don’t forget about safety and mounting. An electric fuel pump should always be mounted as close to the fuel tank as possible and below the level of the tank to help with priming and to prevent vapor lock. Make sure the pump you choose is designed for your type of fuel system, whether it’s a return-style or a returnless system. Taking the time to choose the right adjustable electric fuel pump for your 55 Chevy will pay off with reliable starts, consistent performance, and the peace of mind that your engine is getting the fuel it needs.
FAQ
Why should I switch to an adjustable electric fuel pump on my 55 Chevy?
I made the switch for a couple of big reasons. First, reliability. Mechanical pumps are driven by the engine’s camshaft, and if that arm wears out or the diaphragm fails, you’re stranded. An electric pump gives me a consistent fuel supply the moment I turn the key, which helps with starting. Second, and more importantly, is adjustability. If I change carburetors or add performance parts, I can easily dial in the exact fuel pressure my engine needs for optimal performance, something a fixed-output mechanical pump can’t do.
What is a safe and effective fuel pressure for my carbureted 55 Chevy?
For most classic carburetors like a Holley or an Edelbrock, you want to stay in the range of 4.5 to 7 PSI. I usually start at around 6 PSI and then fine-tune from there. Going over 7 PSI is risky because it can force the carburetor’s needle and seat open, flooding the engine and causing it to run overly rich. An adjustable pump lets me set it perfectly and check it with a gauge. Consistency is key here for smooth idle and good throttle response.
Can I install an electric fuel pump myself?
Yes, you absolutely can if you’re comfortable with basic wiring and fuel line work. The most critical part is the wiring; you must use a relay connected to a switched ignition source and include an inertia safety switch. This switch will cut the fuel pump in the event of an accident. Mounting the pump near the fuel tank, away from exhaust heat, is also vital. If you’re not confident with these tasks, it’s a job best left to a professional to ensure it’s done safely.
How do I deal with vapor lock after installing a new pump?
Vapor lock was a constant battle with my mechanical pump, especially on hot days. An electric pump, especially one mounted back by the tank, largely solves this. The electric pump pushes fuel to the engine instead of pulling it, which is much less likely to cause fuel to boil in the lines. If you’re still having issues, make sure your fuel lines are routed away from heat sources like headers, and consider adding a heat shield or switching to a dedicated return-style fuel system to keep the fuel circulating and cool.
Are these pumps noisy?
Some can be, but many modern rotary vane pumps are surprisingly quiet. I barely hear mine from inside the cab of my 55 Chevy. The brushless models are even quieter. The mounting plays a big role in noise transmission. Using rubber isolators between the pump bracket and the car’s frame can dampen a lot of the hum. If noise is a major concern for you, look for a pump that specifically advertises quiet operation.
What maintenance does an adjustable electric fuel pump require?
They are pretty much “set it and forget it” compared to a mechanical pump. The main thing I do is regularly check and replace the inline fuel filter. Debris in an old tank can quickly clog a filter and make the pump work harder, shortening its life. It’s also a good practice to visually inspect the wiring and connections once in a while for any corrosion or chafing. Other than that, a quality pump should provide years of reliable service with minimal fuss, making it one of the best upgrades for my 55 Chevy models.
