Fuel Pump need a Blast Tube?

Measure fuel temperature at the pump entrance and the pump exit, and we'll all know.
It's not a wiseguy answer. Those temperatures are the only thing that counts. However, temperature measurement seems to be rare. Most pump shroud installations are prophylactic (and perhaps unnecessary), or installed as an experiment after a suspected fuel vapor incident.

Data Logger
Dan, can you recommend a good data logger for collecting T data? I've been looking at this one:

Sorry Dave, I've never used one. Datalogging for me has meant a clipboard, or the GRT EIS.
Go for it.

Nice specifications, but no mention of sample rates. I have used the Omega 2 channel K/J handheld for a few years for various things. No logging, but temps should not be changing that quickly to write down. Although it is "proper" to place thermocouples in the flow stream, you can take the bead type, or shielded, and tape to the metal fitting with some conducting grease and wrap with some insulation and aluminum foil for temps within a few degrees F. I have checked this in a lab for engine work. When in the field, the more crude method will data good enough for diagnostics. Obviously, don't ground the bead. My phase I plan is to just epoxy the beads to the fittings/housings for validation. Just wrap with a little fiberfrax and tape - a thermal band-aid.
