My Magnafuel 275 is leaking again. The wife and I took the Dart to town and ate then went to the park and walked, probably put 60 or so miles on it. I noticed the pump was really loud waiting at a light on the way home. When we get home I pull in the shop and it's dripping fuel on the floor. I rebuilt this pump last fall, new bearings, seal, cup and rotor, it cost about $90 to go through it.

I need a pump that can be mounted laying down and live on the street. No more Magnafuel pumps.

Aeromotive 11213
More than plenty for your car
Continous duty doesnt bother it. Will be the next pump i get when i upgrade motors

Edit....... for overkill, the A1000

It sounds to me that you need better inlet plumbing too. If you don't improve the delivery than don't expect any hi performance pump to live under those conditions.

I say this because you said it was getting louder on the way home...classic sign of cavatation which will kill all pumps after the pump is warmed up.

Do you have a bypass on it? any race type electric pump on the street needs a bypass or you will burn it up - the pump dead - heading against itself constantly - just makes too much heat - with a bypass regulator the fuel itself acts as a coolant on the pump

Yes the pump has a bypass built into it with a return line to the tank. I'd think the 10AN feed it has would big enough.

Two different cars over the past 12-14 years and the only pumps I’ve used have been BG400 pumps. They have treated me well with pump gas, race gas, and alcohol.

Do you drain the fuel system in the winter and leave it sit dry? There is a small rubber donut seal in the pump,that you probably saw when you rebuilt it. If that seals drys out from the fuel, the seal will leak.

P.S. John,you must be one of the chosen one's,because those BG pumps were pos. I had 2 of them fail within a week of each other.

I hear ya. I bought one from a guy that had issues and bought a seal kit from a guy on racing junk because BG wouldn’t sell the rebuild kits. I think a big issue with them is people don’t plumb in the return line as instructed and they suck air. It must dump in the top and dump below the fuel level.

I have had Holley pumps over the years, never done anything at all to them in the offseason, never a single issue...... blue, black and 250 Volumax. And i am old and have had a bunch
That said the aeromotive stuff is nice too and is continous duty friendly. Would run that stuff.
Heard more guys whine or have issues with Magnafuel than pretty much anything. No thanks. Pay more, car doesn't go faster, generally WAY overkill.
Holley black can handle the needs of 95% of the members of this board.

My car is a street/strip deal, pump 93. I normally drain the fuel every fall when the weather gets bad. I rebuilt it last fall and replaced the o-ring, seal, bearings and cam/ring assembly.

Magnafuel doesn't build the motors for their pumps, the bearings are metric. The bearings were in the $20-$25 range each, I found them on the bag for $8-$12 for 20.

I ran the pump today and it sounded normal and didn't leak so apparently when it get's hot it leaks. I have a Holley billet 150 that I can run if needed.
