The reason I did this with mine was (1) it has two fuel pumps and only the lower one was going bad and (2) I didn't have the money to buy both new pumps at the time (no sense in replacing one when the other is the same age and has the same mileage). Yes, I agree - it is very dangerous and just as easy to replace but if you are in between paychecks and living on ramen noodles this will do in a pinch .
