575 sci fuel system upgrade
 
picked up a 36 spectre with 575sci 's this past fall that are stock with about 300 hrs on them, pulled motors to do top ends and would like to upgrade fuel system to aeromotive pump and regulator. The question is which regulator to go with, plan on keeping the motors fairly stock for a year or so to get used to the boat but would like to have fuel system upgrade done and get away from the merc lift pump and vst setup as they apear original. thanks

Weldon pumps are quieter (1100A) and aeromotive regs. Do you plan on keeping those blowers on there?

Weldon prides themselves on being able to lift as well according to their marketing dept.

i just did this,*along with a few other things* went with the Weldon 1100A pump and a aeromotive regulator 13101 with the Eddie young EFI plate to remove all the factory stuff
ran amazing on the dyno

If you have stock mapping in your ECMs it might be a good idea to get them to Eddie young for remap. They are pig rich and will leave your transom black. No more high idle on startup, everything gets better.
