Overview

The Early Model Lycoming Fuel Pump
(40174/40295 low pressure, 40595 medium pressure, 40296 high pressure)
In the spring of 1964, AC introduced the first dual diaphragm type fuel pumps. These pumps were the first models to incorporate the oil seal integral with the upper diaphragm and a separator ring for installation of the vent / overboard drain line. These pumps are characterized by a rocker arm which is an early riveted, laminated design. Current production in Lycoming pumps will not fit some pre-1978 applications without expensive modifications. You can eliminate the need for these modifications by ordering an FAA Approved overhauled early model pump for direct replacement.

The Late Model Lycoming Fuel Pump

During August of 1978, AC introduced what is now known as the "late model" fuel pump which has a "channeled" rocker arm. This pump is taller than the early laminated arm pump and has a unitized diaphragm assembly. Because of its increased size some pre-1978 model aircraft require expensive and time consuming modifications to carburetors or accessory housings (ref: Lycoming Service Inst. No. 1110C). These modifications are not required if our smaller, early model laminated fuel pumps are installed on your aircraft.

Q: What is the difference between the LW15473 and the AF15473? Both are rated for the IO-360 which is fuel injected and appear to have the same pressure ratings.

The LW15473 is taller than the ADF15473 pump. They may not fit all the same applications due to the size.

Q: What is the flow rate of the fuel pump LW15473?

The flow rate of this fuel pump is 45 GPH (gallons per hour). The operating pressure is 24-30psi.

Q: What is the difference between the LW15473 and the LW15472?

LW15473 is a high pressure fuel pump and LW15472 is a low pressure fuel pump.

Q: What is the flow rate on a LW15472 fuel pump?

We could not find any info on flow rate, but the application chart lists this unit as 4-6 PSI.

Q: Im hoping the AF15472 is an exact replacement for the LW15472. Is this true? Does the AF15472 come with a gasket?

Yes, the AF15472 & LW15472 are the same, and the AF15472 does come with a gasket.

Q: Does the AF15472 have a laminated arm?

No, AF15472 has a channel arm.

Q: What are the dimensions for the vent port on a Tempest LW15472 fuel pump - thread size and 37 ft flare? Or part number for a right angle fitting for the vent port?

The two large ports are 1/4npt and the small port is 1/8 NPT. You would need to determine the correct fitting for your application.

Q: Does the Tempest Fuel Pump, Part Number AF-15473, come with a gasket?

Yes this does ship with a gasket.
