A fuel pump is an important component of your car’s fuel system responsible for taking fuel from the fuel tank and sending it to the engine for combustion and power generation. If you are reading this review article then it means you need a replacement of your fuel pump and you must have heard a lot about Precision fuel pumps, but you want to clarify their worth. 

As you read this post further, you should expect a detailed Precision fuel pump review that covers its features and performance. After reading this, you should be able to determine whether this product is the ideal choice for your car or If you need something else.

Precision fuel pump review

This Precision fuel pump review explains the primary features of this product like its mounting type, flow rate, fuel compatibility, and what kind of fuel pump it is. 

Type of fuel pump

The fuel pump by Precision is an electric fuel pump, but there are 2 types of electric fuel pumps: inline and in-tank fuel pumps. Inline fuel pumps are positioned outside the fuel tank instead they are located in the fuel line so they can push fuel to the engine. In-tank fuel pumps on the other hand s located inside the fuel tank which houses the fuel. The fuel pump pulls the fuel into it and delivers it to the engine. 

Because the Precision fuel pump is an in-tank type, it will make less sound when operating and it will be more efficient compared to an inline pump.

Flow rate


The flow rate is the amount of fuel a fuel pump can deliver to the engine in a certain amount of time. This feature is important to determine how your fuel pump works with your car to ensure maximum performance. If the flow rate of a fuel pump is just right, then It delivers enough fuel on time that meets the fuel-to-air ratio and makes combustion happen. If the flow rate is too high or low, then it reduces or increases the fuel-to-air ratio which ultimately affects combustion and performance.

This product has a flow rate of 61 gallons per hour (GPH) or 230 liters per hour (LPH) which makes it a high-pressure fuel pump delivering 1 gallon o fuel per minute which is an impressive performance. A flow rate like this makes this fuel pump suitable for modern and high-performance cars. 

Number of terminals

The terminals in a fuel pump are the electrical connections that make power and control possible in your car. This fuel pump has 4 terminals, 2 of which are positive and negative. The positive terminal supply power to the pump from the battery while the negative terminal is connected to your car’s electrical ground which allows it to operate. 

The other two terminals are the fuel pressure and fuel level sensor which give you more information about the electronic control unit (ECU) for optimal performance. 

This fuel pump has a male terminal that connects to the positive terminal or power supply of your car. 


Other materials included in this product that guarantees its performance include the strainer and tank seal. The strainer ensures that as the fuel pump takes fuel to the engine, it doesn’t include any dirt or debris. Tank seals are accessories that ensure your fuel pump last longer as they are made with high-quality materials that are resistant to fuel blends that can cause degradation. 

The inclusion of these accessories gives you all you need in one package as opposed to purchasing them individually from auto shops. 

Pressure rating

The pressure rating for this product is 84 to 90 PSI. This implies that the Precision fuel pump is best suited for modern engines like the GM LS engine. A carbureted internal engine requires a mixture of fuel and air to generate power and this kind of engine needs low fuel pressure of about 4 PSI. Using this high-pressure fuel pump for this kind of engine will cause both short-term and long-term damage to your car. 

Modern engines are called fuel injection engines and it uses a high-pressure fuel pump to meet a car’s performance requirements. These kinds of engines usually require a fuel pressure of 60 PSI to 80 PSI to contribute to the production of horsepower by your car. The fuel pressure ultimately determines the flow rate this product provides. 

However, while the Precision fuel pump displays its fuel pressure to be accurate and suitable for high-performance cars, several reviews prove otherwise. Several buyers have complained of the inaccuracy of the pressure rating which affected the performance of their car. 

Outlet thread size

The outlet diameter of this product is 5/16 inches which is also a 4 AN (Army-navy) line. This means that the outlet of this fuel pump is designed for high performance and has a male terminal which is connected to the positive terminal. Based on reviews, the Precision fuel pump outlet will work with your vehicle’s stock connector. 



With the pressure and flow rate of this product explained, Precision fuel pumps are best for GM or high-performance cars. This fuel pump is compatible with just gasoline or diesel and using another kind of fuel it isn’t designed for will cause it to wear faster and fail. Beyond cars, this fuel pump can also work with suitable trucks, boats, and lawnmowers. 


The Precision fuel pump has received a lot of positive feedback about being easy to install. If this fuel pump is compatible with your vehicle, you won’t need additional installation materials. Depending on the model of this fuel pump, the fittings included can be universal or vehicle specific. 


The Precision fuel pump lies on the more affordable side when it comes to cost, and it won’t take a huge toll on your budget. Its affordability is one of the reasons a lot of buyers choose this product, and for some, their experience with it was great and worth the price.


Final verdict

The Precision fuel pump may be one of those fuel pumps that has popped up in your browser or as a suggestion when looking for an aftermarket replacement, and after all our research, we have discovered that some customers seem to be satisfied with its performance and others didn’t like it.

Several users complained about a cranking noise 2-3 months after installing this product and about how it lacked quality and didn’t do justice to its description. For others, this fuel pump served them for years while delivering optimal performance.

With an average rating of 3.5, the Precision fuel pump is not the worst option nor the best. If you want a fuel pump that lasts for a long time and you prioritize quality and pressure rating, then this product may not be worth investing in and you can certainly go for better fuel pumps. However, If you are on a budget, and you need a fuel pump to take you for some time and in some cases a long time, you can purchase this product. 


There are a lot of aftermarket fuel pumps out there and seeing as this component of your fuel system is very important, you want to select the best product to meet your vehicle’s needs and still maintain performance. You may have been recommended the Precision fuel pump based on your budget and vehicle’s requirement, but is it worth the investment?

This Precision fuel pump review discusses the features of this product, and among other features, we looked at the pressure rating, flow rate, compatibility, and installation. Based on these features, we recommend that you invest in a better fuel pump If you are thinking long-term and that you invest in this product if you are working on a budget and thinking short-term.
