Retain the middle digits of the diaphragm number

3C7-04005-0 and 3C7-04029-0 are both identified as fuel-pump diaphragms, but they remain separate references. The shared 3C7 prefix does not resolve the choice. Compare the complete schedule number, including its middle digits, when selecting the diaphragm rather than relying on the engine make alone.
