FSD - Acceptable Temperature Range

[MEdlin]

Does anyone know what the acceptable temperature range is for a normal FSD? I asked the guys at Diesel Injection Service, a Stanadyne authorized service center, and they had no clue. I'm seeing 155 F on my new FSD when mounted to an external cooler.

I emailed the same question to Stanadyne and received a reply from one of their engineers. The acceptable operating temperature range on the DS Electronic Pump is -40 degrees F to + 240 degrees F.
