Ford SSM 500089 (5.0 2017-2021)- Errors P0087 and P008A

[Cobra Jet]

If anyone is getting error codes P0087 or P008A after doing any mods or service to engine, fuel injectors and experience loss of power, stalling, etc., etc. check your fuel line that connects the high-pressure fuel pump to the port injection rail, it has a specific orientation per SSM50089 (attached).

I suppose this is why the Whipple manual is adamant that you only disconnect from the rail and not the pump
