I am looking for a straight swap in tank fuel pump for around the 450-500 hp mark, should I use the aeromotive 340 or the Walbro GST 450K (455 LPH)? has anyone had experience with either?

With my 450 I had to change to a heavy duty regulator as it was flowing a lot of fuel, some also recommend changing the return feed. We instead added another line from tank on a split feed I believe.

Why not go Walbro 400? Or even a twin 255? Plenty of options.

sounds like the aeromotive may be the way forward I just read a thread with someone saying they had had one fail.
