Amsoil SDF26

It has both an internal by-pass valve, 7-9 psid and an anti drain back valve ....same thread and gasket as the SDF-15/96. Length is 7 1/8", vs 5 1/4" for the SDF-15 ....

thanks, I use it in an application that calls for the SDF15. I received two by UPS today, and I couldn't see a drainback valve through the inlet holes as per most filters(i.e. rubber/silicone flaps)...is it internal on these puppies?

I just talked to the tech line, and he responded that the anti-drainback valve is further up in the SDF26.

This explains why I cannot see it through the inlet holes.

Can anyone verify this different design?

I would really hate to have to cut one of my new filters open...

Can anyone tell me if this filter has an anti-drainback valve?

thanks, I can't find a spec sheet.
