Product Details
- Unconditional one year warranty
- Internal check valve to prevent backflow
- Modern solid state pump – More dependable and uses less current than the old breaker point pumps
- When this pump is installed the existing connector in the aircraft is re-used.
- 24 Volt system
- The 3 amp circuit protection kit is not included with this pump.
- This pump will not operate from a battery charger. It must have a battery DC current.
- Replacement filter kit p/n CA42370
* Not approved for use in fuel injection aircraft.
Important Notice
This pump has most of the factory test fluid removed for several reasons:
- Many shipping carriers do not want the pump to be shipped “wet”.
- It reduces the likelihood of leakage during shipment.
- Most importantly, it helps avoid contamination of systems such as fuel systems with a non-fuel product.
One result of this is that, during installation, the pump internal cavities must be flooded with fluid (fuel, alcohol, etc.) in order to properly pump upon startup. Large amounts of air in the pump (air locking) will prevent the pump from initially pumping properly.

Frequently Asked Questions
I have just installed my new Fuel Pump and my engine will not start. Why?
A common cause for this problem is fuel starvation due to improper installation of the fuel pump. Make sure that the fuel lines are not crossed; that is, the inlet line should be connected to the inlet side of the pump (marked “IN” on the top of the port) and the outlet line should be attached to the fuel pump outlet port. Fuel should be present at the inlet side of the fuel pump. Improper installation of the fuel pump may result in a misalignment of the operating lever with the operating plunger in the accessory case. If so, there will be no movement of the lever and no pumping motion to provide fuel flow. If misalignment is found upon removal of the pump, the lever is probably damaged or broken. If misalignment of the operating lever has occurred, it will require inspection and repair by a qualified technician.
What is causing the fuel (or oil) to leak from my Fuel Pump drain line?
Leaking fuel or oil through the fuel pump overboard drain line indicates the rotary seal is running dry or contamination happened in the field. Your fuel pump should be replaced before further flight.
What is causing my fuel pressure to fall below the “green arc”?
The most common reasons for low fuel flow/pressure are the following: A worn or broken O-ring on the inlet side fuel fitting can cause an inlet suction leak. An inlet air leak will result in low Fuel Pump output pressure. A weak operating spring in the Fuel Pump diaphragm assembly A worn fuel pressure gauge A clogged fuel vent or fuel cap A constriction in a fuel line either externally (a kinked hose), or internally (due to a collapsed hose lining) Wrong fuel pump for the installation
What is causing my fuel pressure to fluctuate?
Fluctuating fuel pressure can be the result of the following: A worn fuel pressure gauge A worn or broken O-ring on the inlet side fuel fitting An obstruction in the induction system (air intake) A clogged or dirty fuel strainer Foreign material inside the fuel body (such as fuel cell sealant, thread sealant, or a drill shaving)
Is there a mandatory replacement time for diaphragm fuel pumps?
Diaphragm fuel pumps should be replaced or overhauled:At engine TBO or after ten years in service, whichever occurs first. Replace on condition if leaks develop or performance drops for example.Refer to Lycoming Mandatory Service Bulletin 240W for information regarding engine TBO.
