Dual Bypass filter system

I am considering building my own Dual Bypass. I have my bases and mounting figured out but I don't know how these things mount and are plumber. Could some one with this type of kit post some pictures and descriptions showing the plumbing and such. Any help will be appreciated. Thanks

Dual bypass seems excessive. The biggest problem with oil in a 6.0 is the viscosity (it shears it down to 30 weight pretty quickly), not particles

I have a 7.3 though. I have heard good and bad things about the dual bypass. doinga single would make no differance than just putting a better filter in place of the stock. Any ideas

A single bypass does not remove your standard oil filter that is on the block. There are ports on the filter housing on the block where you would attach your feed and return lines for your single kit. So you will still get the filtration of your standard filter and then the much finer (2-3 micron) bypass filter. From what I have read and been told the dual setups are no longer recommend for use of the 7.3. Even Amsoil no longer recommends using their dual filter kit on our 7.3's. I personally don't feel that it is worth the risk in running one of them. And as far as I know the single and dual kits should filter just as good as one another (so long as you use the a good filter on the block), but don't quote me on that.

Hope that helps,
Mike

Where did you here or read that? I have been on the AMSOIL website and there is no mention of it as far as I read. I did read where they say its not recomended for the 6.0 though. I was just talking with a local AMSOIL rep today and did not mention anything about them not being recomended.

I have the dual Amsoil set up and love it. I couldn't find anything on their web site about not using the dual on the 7.3 either.

I just put 15 quarts of AMSOIL 15W40 and AMSOIL filter in mine. I didnt realize that the dual bypass system deleted the filter on the block. I am ordering my mine tomorrow. The dealer said I should see an increase in mileage as well. I am going to go full synthetice with erverything eventualy. I am trying to do everything to squeez the most mileage out of my truck as possible.
