Transdigm purchased Dukes a few months ago.  My neighbor has close ties to the old Dukes ownership.  It appears from Transdigm’s pricing policies, that the Dukes product line is not long for this world.  I am very interested in the Weldon/Dukes interchangeability.  I anticipate we will be forced to do something in the near future.

Russell Steiner, I just experienced a similar fuel pump problem in my IV-P.  The low boost failed to operate on a recent flight.  It turned out to be the “low boost switch” and not the pump.  I found that if the switch was pushed “full on” it did not supply voltage to the pump.  By moving the switch slightly towards the off position, it worked just fine.  I replaced the switch and all is well.
