I am now running an Aeromotive A2000 and an Aeromotive 4 port bypass regulator, probably overkill but wanted to be safe. I think the meltdown was caused by a clogged Aeromotive fuel filter, my bad for not checking it sooner. It had an Aeromotive A1000 and a 2 port bypass regulator. Some here on the boards thought that was borderline for 1000 hp. I traded someone on yellowbullet straight up my A1000 for the A2000 and bought the reg. new.
