    • The J-39021 sets can also be used for other car fuel system diagnostics (see my listing #266688999662 for J-34730-E).

    All are used but in NICE condition. J-41990-A gauge runs smoothly and accurately, J-39021 lights when powered and is very clean with crisp switch actuation. Three of the five pieces in this lot are now obsolete and gone from the OEM’s catalog, and
