420A Fixing a mess.

[Natas Eclipse420a]

Hey guys so im currently fixing a mess and doing some research currently my eclipse is using apexi controllers and the harness is a mess...in an attempt to clean all that up i will be putting in a new harness and running a FMU with 12:1 and a aftermarket FPR i watched some videos saying that u can run 440cc injectors with the FMU set to 12:1 and a FPR set to 20 psi my only question is and i have the fuel diagram https://www.dsmtuners.com/attachments/attachment-jpg.445994/ where would i install the FMU and FPR relative to the vehicle and i also would assume that i would remove the stock FPR as well if not delete it this is my first build and i want it to go well i only plan on running 8-10psi of boost nothing serious till i can look into a swap later on. please help!

I would put the AFPR wherever the stock FPR is--it depends on your current fuel line configuration. The rest can stay the same as in the diagram.

The only other thing I would add is this: if you're planning on running a return line in a late model fuel system ("configuration #1"), then I would put the filter on the feed side, not the return. I'm not sure what I was thinking when I drew that...

You can put both the AFPR and FMU in the engine bay, yes.
