My fuel-injected IO346 uses a high pressure boost pump that apparently differs from the fuel injected Lycoming pump and the carbureted engine pumps. The parts book calls for PN 4140-00-11, but that pump does not appear to be available new from anywhere. Is this the correct part number?
According to the Raytheon-Beech Parts Department (RAPID), electric boost pump PN 4140-00-11 has been replaced by PN 1816-00-1. This pump is currently available new from RAPID at the staggering price of $920.71 (plus tax, S&H), or overhauled at an similarly high price of $543.25 (plus tax, S&H). You may want to check the Links for the alternative supplier of overhauled boost pumps (FuelPumpDepot.com). Call them or email them if you don’t see your pump listed on the website.
