looking to buy a quick star 300.

Don't know who has the best pricing on Magnaflow, but I suggest you strongly consider the PE4500 pump from Product Engineering (http://www.productengr.com/PE_4500.htm) instead. The owner of this company has quite a history in electric fuel pump design and manufacturing, dating back to the design of the prototype Barry Grant pump first offered in 1979. Nothing wrong with the Magnaflow but this pump is IMHO as good if not better for less $$$. I also like PE's bypass regulator design better than any other on the market. That being said, I'm still running my whimpy little Mallory Comp 140. If I ever decide to upgrade to a bigger pump it will be this one hands down.

Double post.
