What kind of fuel pump does a six cylinder engine use?
All mechanical fuel pumps used on inline six cylinder and V8 engines are diaphragm type. No adjustments or repairs are possible. The pump is operated by an eccentric lobe on the camshaft or the camshaft gear. On six cylinder engines, the eccentric rides directly on the fuel pump arm.
