Hey guys I bought the bypass system from Amsoil, and looking to install it, but it seems to be crowded under the hood there, any ideas where i could install it?? this is especially for those of you who have installed this unit, or the FAAS one, i would think they are about the same design as to how they mount. i was thinking along the frame, but havent had the chance to look and see if the frame has the bolt holes there to mount it there. thanks for any advice on this.

Seems the frame rail is the most commen place to put it. See if you can mount it as far forward as possible so you don't get any rocks coming off the tires and damaging your filter:) Let us know how it goes as Im looking at getting a single bypass unit from amsoil!

I sure will, I may put a write up on it for others to benefit from it, unless there is another which I will look for first

No I don't believe there is, so yeah that would benefit us all:)

If you have the 7.3 the feed and return ports are already there just have to use the right fittings. I will see what I can find for pics.

Okay haven't found a pic, but its pretty self explanatory. If you are looking at your oil filter the port on the left of the housing is the oil out which would flow to your bypass filter that is a 1/8 NPT. The port to the right of the full flow filter is the oil in that flows from the bypass filter back to engine and that is 3/8NPT.

Cool, so if i use the dual bypass system this way, instead of as it was orginally set up which gets rid of the normal filter, will i still get the same problems the others spoke of in their posts? such as lower oil pressure, and noise. or is this bypass less volume (It would seem to be since the connections are smaller than the current system) or should i swap this for the bmk 11 single filter? thanks for the input and assist on this

Yeah I would recommend you get the single bypass unit because you still keep the stock full flow filter with this application and you would tie it into the truck like I just explained. If you use the dual bypass you are doing away with the stock full flow filter and supposedly this robs too much oil pressure from the engine. Also there is supposedly a harmonics issue with the dual bypass it gives off a high pitch whineing noise from the hoses.

From what I have read this is strickly a powerstroke issue and I guess amsoil doesnt recommend the dual bypass for the powerstroke anymore.

ok, but i do think you mis-understood what i was saying about the dual, i was asking about keeping the main filter and doing as you said using the connections on the left and right. would i still lose pressure of a substantal nature? if so, then i will in fact swap out for the single filter system. i was asking simply because i have the dual on hand, but will switch it as necessary , you guys have had your trucks longer than i have, so i would think you know a bit more than i do. again, thanks for the info

Ok, then single it is, but they still have that one listed in the preferred/dealer catalogue, as the one for the 7.3. they dont recommend it for the 6.0, thanks

Okay I think your saying keep your dual bypass but only use the single filter and tie it in like I said? I think that would probobly work, but you might be better off selling your dual bypass and buying the single and putting some money in your pocket? Not sure. I will get all the info on the dual and single and post it up so you can make an informed decision. As far as I know no you would not lose any pressure with the single bypass as only a little bit of oil is bypassing through the filter at a time. I will get back with all the info as soon as I can find it:)

O.k. swapped out the dual for a single, as soon as I get time I will install and take pictures so I can post a write up on it.
 
#16 ·
Sweet looking forward to the writeup! Im still going to go with a single bypass eventually:p

BMK-13 is the recommended setup for 7.3 powerstroke. Do to low oil pressure amsoil only reccomends single system.

If you go the the amsoil website, click on bypass filters there are plenty of 7.3 pics.

I have done over 10 of them and to fab a bracket and attach it to the frame rail is by far the best way to do it. The rest is simple pull the plugs out of the oe housing and put your lines on. Your major concern is to keep it away from debris and make it easy to change. You can mount it any direction also, so don't be affraid to have the filter pointed towards the back of the truck along the frame rail. This will aid in keeping debris from hitting it and causing a Caution flag in turn 4.:D

I had a welding shop fabricate a bracket for me. There are some holes in the bottom of the frame rail, on the driver's side - lined up with the driver's seat. I had the mounting bracket bolted on there. Just make sure that you make the bracket tall enough so that the bottom of the filter does not extend below the frame rail. I used the Baldwin OB135 mount and am using the Baldwin B164 bypass filter on mine. The lines I had put on are hydraulic lines rated at 5000 psi. Overkill? Yes. But, I don't worry about the lines bursting on me. After you've installed it, drive far enough to reach normal operating temp, check for leaks, and make sure that the bypass filter is getting hot. If oil is flowing through it, it will be.
