FL-2 NYLON FLANGE
Nylon Flange used for mounting the S3 fuel or water sender or S3H holding tank (black water) sender.
Fitted to topside of tank to create 1 ¼" BSP thread. Hole pattern is standard SAE 5 hole
Can be used with VDO-U inner ring.
For mounting in tanks with a thin top it is recommended to use a FL-2 flange together with a FLS-U under-ring (stainless steel) flange to secure against leaks.
The hole pattern on the FLS-U fits the 5 inner holes on the FL-2.
This hole pattern is the standard SAE 5-hole pattern Ø54 mm.
Please note that the SAE 5-hole pattern is not symmetrical.
Turn the parts to find the correct position before fitting the screws. A mark on both parts shows corresponding holes.
When mounting the FL-2, cut a 59 mm hole in the tank where the sensor is to be placed.
Slide the FL-U or FLS-U in place inside the tank, and mount the FL-2 with rubber gasket on tank top.
When all 5 screws are securely tightened, the S3 sensor, with its 2 o-rings, can be screwed into the FL-2 flange.
