Cessna SEB99-18R1 describes periodic checks of the fuel gauging system.

The most common reasons for low fuel flow/pressure are the following:

1. 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.
2. A weak operating spring in the Fuel Pump diaphragm assembly
3. A worn fuel pressure gauge
4. A clogged fuel vent or fuel cap
5. A constriction in a fuel line either externally (a kinked hose), or internally (due to a collapsed hose lining)
6. Wrong fuel pump for the installation

Fluctuating fuel pressure can be the result of the following:

1. A worn fuel pressure gauge
2. A worn or broken O-ring on the inlet side fuel fitting
3. An obstruction in the induction system (air intake)
4. A clogged or dirty fuel strainer
5. Foreign material inside the fuel body (such as fuel cell sealant, thread sealant, or a drill shaving)

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.

We pressure test our repaired valves to a minimum of 5 psi using precision controlled air pressure and a calibrated low pressure indicator. This pressure is above the normal fuel pressure on the valve and below the limits of the springs in the valve. Each valve is submerged in Stoddard solvent while the air pressure is applied to the valve. The valves are then tested in each position to assure that there are no inter-port or external leaks. Leaks are detected by looking for air bubbles escaping from the valve.

Over the years, there were some variations in the original vent lines from Cessna, and variations in the location of the exit hole in the wing. The vent line can be bent a little for proper fit. See the Installation Tips for McFarlane Fuel Vent Lines.

The SunSpot 36LX landing and taxi lights and SunSpot 46LX can be installed with just a log book entry if you can install the light in an existing mount and use the existing wires, switches, and circuit breakers.

The SunSpot 36HX landing and taxi lights and SunSpot 46HX can be installed with the pulse function enabled in any model listed on the AML under STC, or in other aircraft models with a 337 that uses the AML STC as a basis for approval.

If the lights are mounted to an existing mounting location with no structural modifications and existing wiring can be re-used, the lights can be installed with a log book entry.

If there are modifications to the wiring, a 337 should be submitted for approval for the installation.

If there are structural modifications made to mount the lights, a more extensive approval may be required, ranging from a 337 to an STC.

The Pulsar NS has a forward red or green navigation light and a strobe that covers 180 degrees from each wing tip.

The Pulsar NSP has a forward red or green navigation light, a strobe that covers 180 degrees from each wing tip, and a rear white position light.

We recommend 3 conductor 20 gauge shielded single bundle wire. 

Yes, with no modifications at all.

No. Your A&P can install the prop in less than an hour.

We have made the many contact methods available on our Contact page.

Flight-Resource stocks the most popular propellers and can ship to you within 24 hours. A custom built propeller will take 12 to 14 weeks, typical.

MT-Propeller began making natural composite propellers in 1980. Over 50,000 blades are in action with no in flight failures.

It varies based on your location and speed of delivery.

YES!! MT manufactures propeller systems for hundreds of applications and they even custom design and build props for experimental and aerobatic planes. Call for more information.

All Hydraulic blades have available Electric (hot prop) or Fluid de-ice option.

No. Preflight and annual inspections are no different than with a metal prop.

There is no U.S. import tax or duty at this time for props that we ship from our Warehouse. Customs fees and broker charges may apply to props that are shipped from Germany direct to the customer.
