Although vapor lock is almost unheard of today, some older Camaros are still plagued with the problem. Vapor lock occurs when fuel in the metal fuel lines between the fuel tank and fuel pump vaporizes and an engine-mounted fuel pump draws the vapor into the pump causing it to lose its prime. With no fresh fuel being pumped to the carburetor, the float bowl empties out and kills the engine. Some older model Camaros were famous for this because the air temperature under the hood was so high due to the design of the vehicle.

Instructions

1

Locate the metal fuel lines under the hood. Ensure that no modifications have been made to the lines that bring them close to the exhaust manifolds. Reroute the lines away from any heat sources.

2

Wrap the metal lines with foam waterline insulating tubing. The added insulation will keep the lines from overheating.

3

Loosen and remove the bottom two bolts of the fuel pump with a three-eighths-inch drive, one-half-inch socket mounted on a 6-inch extension, connected to a three-eighths-inch drive ratchet wrench.

4

Slip the two bolts through the mounting holes of a fuel pump heat shield. Slide the bolts back through the water pump mount and thread them back into the engine block until they are tight. Ensure that the heat shield is positioned between the exhaust manifold and the fuel pump.

Cam sprocket multi-lock tools hold the cam timing in place while the engine is being overhauled or the timing belt is changed. Most multi-lock tools are a simple design but made to exact specifications to grip the cam and lock into sprocket teeth. The cam is a rotating piece of a machine, a shaft or wheel, designed to strike a lever.

Gates 91008 Cam Gear Sprocket Tool

A cam gear sprocket tool holds the camshaft in position while the timing belt or other gear is removed from the shaft. The tool simplifies engine-timing procedures, especially when re-aligning the cam-timing position. The 91008 sprocket tool is also made by Gates.

Baum Multi-Lock II Tool

The Baum multi-lock II camshaft locking tool locks sprockets into the correct engine timing position while a timing belt is being replaced or the tension adjusted. This tool is especially handy for keeping cam timing set on four-cam vehicles while changing belts. A pitch adjustment feature accommodates varying tooth pitches and sprocket diameters. The design provides maximum horizontal and lateral off-set adjustment. A ratchet lock handle provides powerful lever action in small spaces. This tool is available online or from specialty automotive parts retailers.

AST 4500 Multi-lock II Tool

The AST 4500 multi-lock II camshaft locking tool is an adjustable tool that locks the cam sprockets in place, preserving their timing during a timing belt change or engine overhaul. The tool can accommodate a variety of sprocket diameters and tooth pitches, as well as flanged sprockets. The 4500 multi-lock also locks between cam and diesel injection pump sprockets on certain diesel engines. Assenmacher Specialty Tools (AST) is based in Colorado, and its catalog is available online.
