Holley 12-427 fuel pump

Have not put the Holley Mighty Mite Electric fuel pump into service at this time. Suspect it will perform as to my expectations. Being a user of Holley products for over 50 years I have come to expect quality service and reliability from Holley products.Read full review...

Bad purchase

I bought this pump and installed it as per the instructions. It was on for less than a week when it just gave out and left me stranded. Fortunately I had kept the old fuel pump, which the new was supposed to upgrade, in my toolbox. I reinstalled it and got myself back home.Read full review...
