|HIGH PRESSURE 25 - 30 PSI CHANNEL ARM
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.
OVERHAULED LYCOMING FUEL PUMPS
All internal parts are replaced with new certified parts. The actuating arms are magnetic particle test inspected; cast parts are inspected for wear, corrosion and cracks. Both the older laminated and newer channel style fuel pumps are overhauled for normally aspirated, pressure carburetor, and fuel injected systems.
Note: Customer will need to provide core for overhaul in the event our supplier does not have cores available to overhaul. Additional core charge will apply. Please add pump to cart to see current applicable core charge.

TEMPEST O/H FUEL PUMP 15473
Good Price, fast shipping
Fits perfectly. I dont know if it runs as I have a lot more to do to get my engine running. However, it does come with the gasket and, the actuation arm is laminated steel unlike what others have stated that theirs is stamped steel.
