Installation precautions
 
•  Never re-use O-rings.
•  Coat O-rings with engine oil (10W-30 or equivalent) or silicon oil (NUC silicon L45 or equivalent) but do not apply solvent to them as this may remove the oil coating.
•  Do not allow dirt, dust or foreign matter to adhere to O-rings or other equipment surfaces. Do not use dirty O-rings.
•  Be careful when installing O-rings so tools or operator's fingernails do not make scratches, twist or stretch them. In particular, do not insert them in the fuel tube by making them stretch slightly.
•  When inserting the fuel injectors and pressure regulator in the fuel tubes, be careful not to install them off-center or rotate them.
•  Do not store O-rings in locations subject to ozone, high temperatures or direct sunlight.
