How to Stop Vapor Lock in a Camaro

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.
