The venerable Holley 3310 has been the street carb of choice for nearly five decades. Its 750cfm flow capacity and vacuum secondaries make it the ideal carb for both small- and big-block engines. The problem for most installations is caused by the fact that the 3310 has dual fuel inlets and traditional dual-feed hard line kits seldom fit correctly, and often leak. The new Professional Products braided steel line kit offers an attractive and easy solution for a custom leak-free hook-up.

Each Professional Products braided fuel line kit includes -8AN inlet fittings that attach to the stock 5/8-18 inverted flare bowl fittings, using supplied crush washers to ensure a leak-free seat. The braided stainless line spans the correct 8.8-inches inlet spacing and offers a show appearance with its anodized fittings. There is an integral 1/8-inch NPT fuel pressure gauge port and an optional adapter is available to allow use of a -6AN inlet connection or hose barb fittings for various fuel line sizes.
