NOTE: The steps on this page apply only if you already have installed a powerplant kit and wish to upgrade to the next
generation fuel pressure sender at your own cost. Order the 101690-000 Fuel Pressure Sensor from Dynon and the
remaining parts and hardware in Figure 1 from Van's Aircraft.
Step 1: Remove the 100411-000 Fuel Pressure Sensor from the VA-216 Fuel Return Asy. See Page 46-11, Figure 4.
Step 2: Disconnect the WH-Q143 (BRN) and WH-Q144 (BRN) wires from the 100411-000 Fuel Pressure Sensor. See Page 45-05,
Figure 1.
Cut the spade connector off the end of each wire.
Step 3: Find the 25-pin backshell on the end of the WH-RV12-ROTAX Fwall Fwd Wiring Harness.
Use a multimeter to find the BRN wire going to position 16. Mark the cut end of this wire "sensor".
Use a multimeter to fine the BRN wire going to position 10.
Mark the cut end of this wire "ground".
Step 4: Deburr the edges of the F-00036 Fuel Pressure Sensor Bracket.
Inlarge the hole in the grommet called out in Figure 1 to snugly fit over the
F 4 DTX-S Elbow's end with female pipe thread. Use the method described
on Page 31-02.
Insert the grommet into the large hole in the fuel pressure sensor bracket
as called out in Figure 1.
Mount the fuel pressure sensor bracket to the F-1201A Firewall Upper
using the hardware called out in Figure 1.
Step 5: Insert the F 4 DTX-S Elbow's end with female pipe thread into
the grommet from below as shown in Figure 1.
Attach the 101690-000 sensor into the elbow from above using a
small amount of pipe thread sealant.
Attach the VA-216 Fuel Return Asy. to the flared
end of the F 4 DTX-S Elbow.
Adjust the position of the fuel return assembly hose to follow a natural path
to the sensor eliminating side force on the sensor and bracket.
Repace the tie-wrap to the top of the left carburetor if necessary.
See Figure 1.
Step 6: Cut the three wires coming from the sensor 1 1/2 inches
from the top of the 101690-000 sensor and strip the ends.
Use a splice to connect the GRN wire coming from the sensor to the
BRN wire marked "sensor" in Step 3.
Use a splice to connect the BLK wire coming from the sensor to the BRN wire
marked "ground" in Step 3.
Step 7: Find the WH-Q741 (RED) Fuel Pressure Power Wire supplied in the kit . Insert the end
with a d-sub pin into position 2 on the WH-RV12-ROTAX Fwall Fwd Wiring Harness. See Figure 2.
Use a splice to connect the RED wire coming from the sensor to the fuel pressure
power wire. See Figure 1.
