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.
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.
