There was a Carter high-flow on my 300... it has gone out though. I got a new one from Advance Auto Parts (part# 60330). I got the truck to start once and run for a few minutes. It just died on it's own all of a sudden, not I can't get it to start again at all. It tries to catch a little bit, but that's it. It won't start if I use ether down the carb either. The arms on the Carter and Advance pumps are a little different. Anyone know what the deal is, are the Advance/Auto Zone specials junk?
