I have gone through 2 MagnaFuel ProStar 300's in 2 years. Has anyone else had issues with theirs? The first one leaked gas pretty badly after only a few days and the second one just died on me on Monday dueto the bearings seizing. These are $400 pumps and shouldn't be dieing like this... I have sent them off to Magna FUel to be repaired, but this is ridiculous.
