- ...and 69 additional applications
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.
