Enginetech oil pumps are 100% cycle tested for both volume and pressure before leaving the factory, ensuring consistent lubrication performance from the moment of first start. Each pump is engineered to meet or exceed OEM flow rate and pressure specifications for the specific engine application - not a generic substitute. Enginetech offers complementary components including pickup screens, oil pump shafts, and repair kits to complete the lubrication system service. Always prime the oil pump before installation and verify the correct pickup tube fitment for your oil pan configuration. Incorrect oil pressure can cause accelerated bearing wear and premature engine failure - verify part fitment by year, make, model, and engine displacement before ordering.
