Product Details

The Mr. Gasket 1510 Power Valve Block-Off Plug is designed to eliminate the power valve circuit in Holley carburetors when tuning for specific racing applications or troubleshooting power valve failures. This simple plug allows you to disable the power valve function without removing the carburetor from the engine.

Key Features:

  • Direct replacement for Holley power valves - screws directly into the metering block
  • Includes gasket for proper sealing and leak prevention
  • Ideal for race tuning applications where constant jetting is preferred
  • Useful for diagnosing power valve diaphragm failures
  • Allows carburetor operation without power valve enrichment

When using this block-off plug, you'll need to re-jet your carburetor to compensate for the loss of power valve enrichment. This plug is commonly used in racing applications where consistent fuel delivery is required across all throttle positions, or as a temporary solution when a power valve has failed.

Really good prices and fast delivery.

Lowest prices around the web and excellent customer service. The only real issue was the wait between placing the order and when it was shipped. Took 4 days but I chalk that up to the large amount of business they due to their prices being so competitive. For the lowest prices that I've seen I didn't mind waiting a bit longer!

Very fast shipping and product was secure in package to avoid damage....will be ordering from autoplicity again for sure. Also the price could not be beat.

Superb company! Autoplicity had the lowest price, shipped it quickly, and it was exactly as advertised - couldn't ask for better results!

Ordered from here once before got exactly what I ordered fast and and excellent condition. I will be ordering from autoplicity again.
