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.
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!
Very compact and quiet pump
This pump works great on my 79 F100 with a 351M and Edelbrock 4 barrel. The only time I hear any pump noise is when the key is turned on before the engine starts and even then its barely audible. I also recommend using the fuel pump wiring harness that Jegs offers to make installation a little more painless.
