Product Details

The Moroso 65397 is a precision-machined billet aluminum fuel pump block-off plate designed for Small Block Chevy engines when a mechanical fuel pump is not being used. This equalizing plate provides essential 1/8" NPT and -12AN provisions for connecting vacuum pumps, vacuum gauges, or cylinder head drain-back lines in high-performance and racing applications.

Key Features:

  • CNC-machined billet aluminum construction for strength and durability
  • Black anodized finish for corrosion resistance and professional appearance
  • Includes -12AN male fitting for vacuum pump or drain-back connections
  • Includes 1/8" NPT pipe plug for vacuum gauge port
  • Complete hardware kit includes gaskets and stainless steel socket head screws
  • Allows crankcase vacuum system setup when eliminating mechanical fuel pump
  • Ideal for racing vacuum pump installations on Small Block Chevy engines

This block-off plate is specifically designed for racers and performance enthusiasts looking to maximize engine efficiency by creating crankcase vacuum. When used with a vacuum pump system, it helps improve ring seal, reduce blow-by, and increase horsepower. Note: Installation requires pulling vacuum from a valve cover as well for proper system function.

A+shipping was quick, communications were quick

Best prices online! Ordered a JBA performance exhaust and Airaid intake system for my 06 F-150. Was hesitant at first because I never heard of them but ordering was a breeze and saved me over $100 total for two items compared to anywhere else. Had package at my door in about 24 hours and even selected normal UPS ground shipping. Very satisfied and will definitely return!

Autoplicity was plenty cheaper than competitors for the springs I needed. I was shopping around and left the website after beginning a transaction and they sent me a coupon for 25% off shipping if I would return and purchase from them, which was cool. Unfortunately the coupon code didn't change the price and I didn't receive 25% off, but it was still cheaper than others.

slight hiccup with payment, but paypal triumphed over Amazon!
