Brand new pump leaked as well....Right out the front o-ring fitting. As I am pouring fuel in, I hear fuel hitting the floor...I look underneath and a lot of bad words left my mouth in disbelief...Changed o-ring on the new fitting, added Loctite 567, and it solved the leak after loosing 2 more gallons of race fuel...And it was their brand new fittings....I ordered everything new because I accidentally sent the fittings back with the other pump, and this time I went with a smaller 300....

This pump also must build a lot more line pressure. I had to back the regulator up front waaaay off.

No more MagneLeak for me....
