Supplied mainly in vehicle kits, this standpipe is installed like so:
• If possible, remove the sender unit from the vehicles 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.
