Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Removal & Installation: Precautions
Before removing any fuel system components, displayed system pressure must be relieved. It is not necessary to remove throttle body from intake manifold to remove components.
If fuel hoses are to be replaced, only hose marked EFI/EFM may be used. DO NOT use aviation style hose clamps as hose damage will occur. Always reassemble throttle body components with new "O" rings and seals where applicable. NEVER use lubricants on "O" rings or seals. If component assembly is difficult, use water to aid assembly.
