Stand pipe 2: (Part No: AHZ-035) Figure XX
Supplied mainly in vehicle kits, this standpipe 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 hole 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.
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.
