Vapor lock usually affects carbureted vehicles, running gasoline, with an engine-driven mechanical fuel pump. Fuel-injected vehicles can experience vapor lock. However, it is rare. E85, Ethanol, and Methanol also reduce the risk of vapor lock. The first step in preventing vapor lock is to rout fuel lines away from exhaust parts, heater hoses, etc.

This reduces the risk of Vapor Lock and can make more power. However, there are also a few drawbacks: The system requires extra plumbing. A Return Line means additional hoses and fittings. Return style regulators can’t be used in some fuel systems. For example, a nitrous system with a single pump and multiple regulators set at different ...

Non-Return Style Regulators are common on older vehicles. They are usually used with a carburetor. They are also called “blocking” or “deadhead” regulators.

Different fluids have different boiling points. They also absorb moisture over time. If it gets too hot, it creates vapor inside the hydraulic system. Unlike brake fluid, vapor will compress. This causes long pedal travel, “spongy” feel, and reduced stopping power. To avoid fluid fade, make sure you use the right Type of Brake Fluid. Also ...

How does lubricant affect torque values? Adding a lubricant or even just residual oil on a fastener will reduce the amount of torque it takes to reach maximum holding power.

Fastener Type: Torque Specs: Main Cap Bolt (396-427, 2-Bolt) 95 ft.-lbs. Main Cap Bolt (396-454, 4-Bolt, Inner and Outer)

The clean air flows through the engine, sweeping away fumes and vapor. The “dirty” air is drawn out through The PCV Valve. The PCV valve is connected to the intake manifold by a hose. This applies a Engine Vacuum to the crankcase, drawing air through the system. The fumes and vapor are drawn into the combustion chamber and burned away.

The fluid ports at the bottom of the threaded holes aren't always perfectly centered. This is due to variations in the manufacturing process. It will NOT affect the operation of the line lock. The threaded holes are designed to use an NPT style fitting. Unlike AN …

Piston-to-Valve clearance is a problem with Variable Valve Timing (VVT). Most performance cams use a Phaser Limiter or Lock to limit or disable the VVT. Intake Manifold and Throttle Body. Porting is a popular option for stock intake manifolds. At 80mm, the factory throttle body won't be a restriction in most applications.

SAE J30R7 is carburetor rated fuel hose and should only be used in limited runs up to 50 psi.; SAE J30R9 is fuel Injection rated fuel hose which can handle up to 100 PSI.
