## Customer Reviews

### ⭐⭐⭐⭐⭐ Great fuel pump
*by D***3 on April 19, 2025*

Used this because I put a fuel cell in my 95 Jeep yj! Best pump I’ve found for the price. And have had no issues with it for countless miles of off road abuse!

### ⭐⭐⭐⭐⭐ Quality
*by A***N on July 30, 2025*

It was packed good and seemed to be a quality product. I didnt use it due to that not being the issue.

### ⭐⭐ Pump okay but fuel filter regulator is poor quality.
*by V***. on November 26, 2025*

It would be 2.5 stars because the fuel pump was good and fuel filter regulator was bad. Took 4 hours to figure out why my tuning was all over the place. It was swinging between 70 psi idle and 90 psi when voltage picked up because of rpm gain. Never touched the standard 58 psi as it is designed to do. Now I have to go back and rework fuel system.
