How To Identify Fittings - Getting Fit - Tech

While this looks like an ordinary barb fitting, it is unique because it has the unusual threads found in Stromberg 97 and early Ford Holley carburetors.

There are a variety of adapters for later-model carburetors that allow the use of AN lines rather than the OEM-style inverted flare style.

On the subject of Stromberg 97s, Dick Crawford makes these cool combination needle and seat/barb fittings that swivel to make connecting single or multiple carburetors easy. They also come oversize so stripped float bowls can be saved.

Teflon tape has many legitimate uses; unfortunately, it's often seen as a cure-all for mismatched components and improperly formed flares. In addition, care must be used when applying the tape to ensure it doesn't end up inside the system being sealed.

A simple trick to keep copper oil pressure lines from fracturing is a vibration loop (plus it looks cool). Wrap the tubing a turn or two around anything cylindrical.
