I just bought and installed the Magnafuel 300 pump late last year. While driving a couple days ago, i noticed it seemed louder than i remembered last year. After the 30 minute drive and once back home, I felt the pump. It was very hot, hot to the point it was uncomfortable to keep my hand on it. I called Magnafuel and asked if that was normal for the pump to be that hot. They told me to check it with a temp gun and it should not be over 140* and 130*-140* is normal. Also, not to run for more than 1.5 hours at a time without shutting it off. I don't like that as i street drive alot and this is looking like a very unreliable pump. When it breaks, i will be replacing with something different.

This is the Holley pump I have. https://wororww.holley.com/products...bureted_electric_fuel_pumps/parts/12-150

I ran it a couple years on my 408 then replaced it with the magnafuel, very happy I didn't sell it. I've been 6.25 @ 110 with it and driven a bunch on the street. Heck I went 6.57 with a old Holley blue pump and a 3/8" line bent like the factory line, still have it too.

One thing that confuses me.....Magnefuel 275gph rated for 750hp max, the 300 is rated at like 850hp and the Holley is 125gph and rated to 900hp...

I don't think I am over thinking it. I think I do not want to buy another Magnefuel based on the feedback here and have exactly the same failure in a year or two. I didn't realize so many others were having the same issue. Plus, I rebuilt it, and I seem to be missing somthing because its still leaking. And I will tell you what, having the pump fail is one thing, having fuel all over a hot car and pavement is another. It dumps the tank every time this happens.

So finding a suitable alternative is kinda my thinking at this point in the game, but I am not totally sure. When you look at flow numbers and rated HP and nothing makes sense when comparing manufacturers. What flow do I need to make sure 850hp is just fine? I know an A1000 will cover that, and at 4amps less current draw.....Its the only other BIG pump I have experience with. And it was so good, I sold my spare I had for almost 10 years. That style pump, just does not lend it self well to installing it in my Duster and its not just the price of the pump anymore.
So I will call Magnefuel today and see if they can save my butt....Or maybe we try an A2000 pump....Not sure at this point. This sucks and I am almost out of time.
