There's a FAA service difficulty report out on
Dukes fuel pumps as installed in a DA40.
From the sounds of it the pump is in the engine
compartment in this installation.
In a IVP it's typically on the firewall or on the
floor on the co-pilot side.
I was about to put down some sound insulation and
carpet over this but now wondering
if there could be a problem with heat.
Any IVP drivers
a) fly for extended periods with low boost
on
b) have the pump buried
c) did or didn't have problems with
it?

Diamond DA40F
Failed Electrical Fuel Pump
Before the next
student’s flight, the electric fuel pump (Dukes p/n 5100-00-20 installed on a
Lycoming O360A4M) was found inoperative. Inadequate cooling is believed to be
the source of the malfunction. The submitter suggests providing ram air for
proper cooling of the fuel pump and motor.
Nine pumps
installed on four identical aircraft were discovered failed. Time in service
ranged from 102.3 hours to 593.2 hours and averaged 317.2 hours since
overhaul.

Time: Various.
