Standpipe 2 (Sender Unit Pipe): (
Part No:
AHZ-035)
Figure XXI
Supplied mainly in vehicle kits, this standpipe (or sender unit pipe) is installed
like so:
•
If possible; remove the sender unit from the vehicle’s fuel tank, this
will make it easier to attach the nut securely back onto the standpipe
•
Drill a Φ6 ± 0.2mm hol
e into the sender unit
•
Remove the nut from the standpipe and feed it through the hole
ensuring the rubber ‘o’ ring remains on the standpipe ‘head’ side
•
Replace the nut on the standpipe to secure it safely to the sender
unit.
•
Replace the sender unit into the fuel tank.
•
Alternatively, to use in a marine application, simply tap an M6 hole
into the fuel tank, and screw the fuel standpipe with O-ring inside.
The bottom of the fuel standpipe should be 30-40mm from the bottom of the
fuel tank to allow enough suction of fuel and at the same time not allow
impurities and sediment to be drawn up the standpipe.
