[AT] CAV Fuel Injection was Standard Ricardo Fuel Injection

[James Peck]

Looks like CAV became Lucas which became Delphi. Delphi headquarters are in Troy, Michigan right off I75.

Does this pump look like the one on Guy's AC ED40?

Cecil Bearden AT List member, Oklahoma farmer, and Professional Engineer (crbearden at copper.net); The Perkins A3.152 engines I worked on had a CAV pump and used an injector set at 1750 to 1800 PSI cracking pressure.  If the pump was a little weak we would drop the cracking pressure down to 1600-1650.  It would help starting if the tractor had a good battery.   It advanced the timing of the injection some.  By lowering the injector cracking pressure, we could make a weak head/rotor combo last another  200-250 hours.
