Fuel pump is a brand new Bosch 044 with a pre and post- filter. It runs directly from the battery (boot mounted) via a heavy duty relay, so only a few feet of cable. The MSD loom has a fuel pump relay output switch and I'm running that to the relay in the boot, so that line should have no load on it whatsoever:



Pre filter, Bosch 044 pump and big post-pump filter.



Fuel pump relay powered directly from battery. Triggered by low-load fuel pump output in the MSD custom loom.
