I was at the local Car Quests' "filter days" (customer appreciation) and I ordered a base, and full bypass oil filter. ~$13 for the filter, ~$15 for the base. I believe the filter is a two quart size.

I am planing on placing it behind the transfer case. What length hoses, orphases, and fittings will I need.

 

One word of advise I have for you is to make darn sure that you mount the bypass as close as possible to minimize pressure drop (read as "oil flow reduction") into and out of your bypass system. Even if you have to build a bracket... mount it as close as possible. When I installed my OilGuard system, one of the hoses ended up being about 12 inches long, and the second one was about 15 inches long.

I'm surprised your parts didn't come with fittings. The only bypass systems I've seen come as a complete package (with the possible exception of a mounting bracket). Not knowing anything about your setup, and not having had to buy my fittings separately, I can't provide any specs for you offhand.

 

I thought that I would need to put an orphace in the system to restrict the flow to the filter. It is a true bypass system, and not assosiated with the full flow oil filter...

I ordered two filters and a base for it, that's it, I need to figure out fittings and hoses to plumb it into my engine.

 

If it is a true bypass arrangement, the orifice should already be a part of the filter head design, and the documentation with it should talk about how much "bpass" it is designed for (5%, 10%, etc.).

 

Sneak,

I've got a similar system on mine. See my gallery for details. If you do it like that, the pressure line is 40 inches, the return is 46 inches.

If you use Baldwin or Fleetguard filters, the orifice is built into the filter itself, and you won't need one elsewhere.

Since it's a bypass filter, pressure drop is not much of a factor. Suffice it to say, if you've got 40 pounds of pressure at the full-flow filter adaptor, you'll have almost that inside the bypass filter on the input side (given VERY little flow), and virtually no pressure on the output side. It's not like you're SUPPOSED to have a lot of flow through a bypass system.

As you can see, the orifice is small.

Thanks Marv, for bringing your experience! I will look for something like that when I pick up the filter. I did see that the filter has only two small'ish holes around the outside ring where yours has 8.

 

Not sure why it wouldn't let me edit my last post... But does anyone know, or remember the size threads you used on the block? Was there a return port on your block, or did you drill out the pan?

 

There is a 1/8 pipe plug on the oil cooler header right above the oil filter then there is a 3/8 pipe plug with a 5/16 square drive hole in it in the block just to the rear of the oil cooler header. Its there along with the coolant drain plug. the coolant drain plug is 1/4inch drive.

Thanks guys.

 

They just now got the parts in and I need an oil change. So I'm going to try to get them to make those lines for me today or tomorrow...

EDIT: I'll take pictures, and I'm going to try to mount it like marv did.

 

What are the Carquest part #s ? I was going through their filter book last night and would like to compare notes..
Here is a link that I've been saving when I get around to do mine.

I went to look at the photos on that link:

Something's "off" with them. The photos red-X'd ARE correct for a 99-03 7.3.

That's why I sent it along.. Your pics confused the heck outta me... Are you sure you're not filtering your coolant?

 

Tom,

Yes, I filter my coolant, too. But that is a completely different filter, with completely different attach points and a different kind of filter. I also filter my transmission fluid externally. I also filter my fuel with an add-on pre-pump. I'm putting the components together to externally filter my braking and steering hydraulic fluid.

I know what I'm doing (at least in these things).

If my pics confused you, then you might do some further research before beginning your proposed project. If, after "answer-averaging", you feel I'm still wrong, please let me know. Start by looking at the "additional filtration" section of my gallery, but only use it to compare what others have done.

I'll be the first to step up and say I was wrong.
