Frequently Asked Questions

Which pump version do I need for my engine?

M8 for Milwaukee-Eight engines, TC 96" for Twin Cam 96", TC 88" for Twin Cam 88", and XL for Sportster models. Confirm your displacement and year in your owner's manual.

Does the M8 pump come with an oil seal?

No — the M8 high-pressure pump requires a separate oil seal (Harddrive part #68-10305, OEM #62400205). Order the seal separately.

What's the flow improvement over stock?

Depending on your engine type, flow increases range from 110% to 236% of stock at various RPM ranges, providing better lubrication under load and high RPM.

What's included in the box?

The pump, 4 mounting bolts, and (on TC and XL versions) gasket, clamps, and fittings. M8 versions do not include the oil seal.

Do I need a new gasket when I install this?

Yes — always use a fresh gasket when replacing an oil pump. TC and XL versions ship with one included; M8 and earlier versions may require a separate purchase.
