Auxiliary or Boost Pumps in 2024

[RandyArizona]

You may find it easier, and more cost effective to "find a new tech."
First question, I have... HAVE YOU looked at/touched the pump in the aircraft itself? What does it look like?
Any numbers on it?
Next: A search is quickly done:
the pump 1426033-3, has been replaced by: This product has been replaced by this part number: C291504-0201
The C291504-0201 has been replaced by: XC18000-B Or in the aircraft spruce website:
Cessna Single-Engine & 337 Aircraft 18000-B C291504-0201 Fuel Boost
08-07083
$916.00

Unless you have angered your mech tech, I am at a loss as to WHY he has dropped the ball here?!
Best of luck in finding a new mech, or finding a new pump..
Regards,
Randy
