Ok I bought a magnafuel pump because the are supposed to be for sustained use and I drive my car on the street some. I got a prostar 500, put it on last weekend and got the car running. I finished up a few things on the car over the week and took it out for a drive yesterday. The pump started to sound terrible, others on the forum mentioned that there pumps were pretty loud too so I figured it was ok. Well, on my way home the car quit because the pump locked up. I tried to start the car and the battery was low and wouldn't turn the engine fast enough to start it. called my dad and he brought our trailer and took the car home. put a charger on the battery and the car turned over fine, but still no pump. got under the car to check power to the pump and it had good power but I noticed that all of the plastic was melted off the ground wire. This pump pumped about 5 gallons of fuel before it died, what is going on Here? 550 dollars for a pump and thats what you get? Anyone else have problems?
