My fuel pump on my 1100rt is in need of replacement. I came across this pump from HiFlow

It almost seems too good to be true. BMW wants around $350,00 and the Beemer boneyard wants more than half that. HiFlowfuel pumps is only $69.00 and comes with a life time warranty. is this too good to be true?? Has anyone had any experience with these pumps? I am thinking of taking the plunge and any input would be appreciated
