## Customer Reviews

### ⭐⭐⭐⭐⭐ It Works. Plain and simple.
*by C***W on June 14, 2024*

So the pros and cons? Well, the pump is built extremely well. The logo and painted case gives it the appearance of a high dollar unit. I wish I could actually see the internals though because I'm willing to bet the impeller is magnificent as well. Overall it performs better than OEM Walboro type units.Cons: fitment, although perfect in the normal horizonal axis,within the pump assembly, is bad vertically meaning the unit fits perfectly into the grommet tube, power connector was spot on, it's just the rubber pump cap does not support being installed without major modification of the fuel pump housing on an 04 INFINITI G35 coupe. After much trial and error, modification and Dremeling, I finally got it to fit within the unit. The pressure it produces is amazing! You can hear the whirl of the pump as you turn your ignition before firing up for cold start.

### ⭐⭐⭐⭐ High pitched noise
*by C***P on August 24, 2025*

Pump works well, builds and holds fuel pressure perfectly, only complaint is a high pitched noise thats audible the whole time the car is running

### ⭐⭐⭐⭐⭐ Good kit
*by R***B on August 24, 2025*

Great kit put it on my 2015 crf250r with an injector and bike hasn't run smoother since Ive had it plus gotnan extra filter
