    Rated 5 out of 5 by from Holley Mighty Mite Easy install and it is one of the few pumps that you can actually use Ethanol, Methanol and other blended fuels with it. Most after market pumps degrade quickly because they are not blended fuel compatible.

    Rated 5 out of 5 by from Holley electric fuel pump Bought this little pump for my hobby 69 Blazer. I don't drive every day so needed a electric pump to help in faster starts. The pump has been working great.

    Rated 5 out of 5 by from Very pleased Running this pump on an 86 fox body. Mild 302 325 horses maybe? It holds a steady 4 psi. My car runs great. Once I start the motor you cant hear it running.

    Rated 5 out of 5 by from Working Well So Far I have not had good luck with some other brands of inline pumps. This one is working okay so far, time will tell. I mounted it at a 45 degree angle per the instructions, maybe this will increase longevity. The others I have mounted horizontal. It is quiet compared to the last pump I had.

    Rated 5 out of 5 by from Quite! I bought the pump to replace a Holley Blue pump that made way too much noise for a street car. When I first fired-up the Mighty Mite I thought that it too was going to be too loud, as well; but once it pumped up to pressure it quited down. I don't hear it at all, except when I first start the car. Works as advertised!
