Dual Walbro 450 99-02
Didn't turn out exactly as I had planned but I'll find out if it works or not. I had bought the corrugated plastic tube from Racetronix but was guessing on the length and ended up getting too short of a tube for the part connecting to the hat. Ended up using a left over 12" tube I had from the first install. Better than waiting a week for shipping from Racetronix and another $17 shipping charge. I'm not a huge fan of drilling holes in the fuel hat for the secondary pump power and ground but I did it anyway and sealed it with a product called Seal All. There's absolutely no way to fit these 2 450s without hacking the bucket, damn thing is tiny inside.

As you know, I am looking to do the same thing. Can you post top and bottom views? Curious to see if you have any issues at low tank levels.

Don't have other pics on hand at the moment, but this setup probably is a compromise in terms of low fuel levels. But it shouldn't be any different than with the single 450 I was running. I had no issues with that but I also wasn't going WOT less than 1/4 tank. My stock pump, the single 450, and now the duals will all be sucking fuel from the bottom of the tank outside the bucket. So I don't plan on going WOT less than 1/2 tank, especially from a dig.

The pressure shouldn't be any more than stock out of boost. But this is OEM tubing and the one I pulled off the single 450 when I disassembled this module looked fine, other than being discolored. Again, I don't like the redundancy of the tube going to the top hat but it shouldn't cause any problems. I'm not spending another $25 to have a tube shipped here from Canada. And I'm not aware of anyone else besides Racetronix that sells these OEM tubes.
