This isn't something that is listed on Spool Performance's website but they will rebuild and upgrade the OEM low pressure fuel pump (LPFP) assembly if provided with the OEM LPFP assembly. I sent them a used assembly and installed their upgraded assembly (see comparison picture). The Spool Performance LPFP assembly includes a secondary pump that's inside the OEM fuel basket that's activated via a 10psi hobbs switch and an activation wiring harness. After the installation, everything works well and I'm no longer getting fuel breakups after 15psi and my fuel trims are great even up to 20+ psi. It's kinda hard to see in the picture but I connected the hobbs switch to the boost pressure line that comes off the charge pipe.
I forgot to add that the harness was too short so my buddy who's good at soldering extended the wiring harness by about 2 feet.
