Works great
Had on my 302 swapped 85 ranger and it worked perfectly for it. Drove it everyday an never gave me an issue. Small enough to mount anywhere near the tank or on frame rail.

Does the trick!
Converted my 69 Firebird to fuel injection but the mechanical fuel pump didn’t cut it. In comes the Might Mite - no more issues! I call this a “Thumper Pump” it’s a little noisy, but does the job!

Performed as stated.
A little loud but not so much that it makes driving unpleasant. Seems to work as it should.

***asaperformance direct **
I used it for 1 day, pump died. Talk to the seller about it he insist that I’m using it wrong I’ve been using Holley 12-427 a weaker pump with only 12” lift, for a whole year. And he insist that Holley 12-428 with a 50” lift can’t be used the same way. It wasn’t 50” away from my pickup on the tank. I’m sure it was just a faulty pump but he just didn’t want to help me out. I would be very cautious buying for this seller (asaperformance direct) no refund or replcement offered. I do have my old Holley 12-427 back in, I just wanted to run the 12-428 so I could bump my pressures up a little but it failed, I get it pumps fail but a day after using it?
