Amsoil Single Bypass Install? - Diesel Forum

Tailgate · 10-02-2009, 03:34 PM

Has anyone done an Amsoil single bypass install on their 7.3L, without tapping the oil pan? I'm highly reluctant to do so, and want to do an install similar to the way the Oilguard goes into the square 5/16" return plug near the full-flow filter. However, I don't think the Amsoil single bypass kit has the right plug for that spot.

Anyone know what I need to buy?

why dont u run the Racor/Oilguard system?? Unless you already own it or its free why run the Amsoil.

You don't need to tap the pan, There are two plugs at the filter housing and on the block that are used for by-pass kits.

To clarify:

1. I have already purchased the Amsoil single bypass kit.
2. Yes, I know that these two ports exist, as demonstrated in your photo (which is KILLER!...by the way). I even mentioned that in my original post.
3. My problem is, it does not look like Amsoil gave me the proper fittings to plug into both of those spots. I *think* I can do the supply port with what they gave me, but I do not believe they gave me what is needed for the return port.

Therefore, my question is...does anyone know specifically what I might need for these two ports to work with the Amsoil installation kit? Maybe it's there, and I'm simply not seeing it properly. The Oilguard kit you displayed uses a different system for attaching the hose to a fitting, and the fittings are different too (I believe). But the concept is the same...I need Amsoil-specific. Just trying to get an answer this weekend versus having to wait until next week to call Amsoil Service Tech Line.

Are you using the BMK-11 kit? If so it looks like they supply it with 1/4" hose, IIRC the threaded plugs in the block and filter base are either 1/4"NPT or 1/8"NPT thread. You may have to go to the parts syore or a home center and pick up a threaded bushing or reducer, depending on the setup. For a reference 1/4" NPT is the same as your typical air hose fitting.

1/8"-1/4" NPT Bushing

1/4"-1/8" NPT Reducer

I'm installing the BMK-21 (the replacement for the older BMK-11). Frankly, they are almost identical setups, just a different filter housing/mount assembly if I'm not mistaken.

OK...realized I'm an idiot (First time ever? Don't think so...). Apparently the plugs that fit into the hose fittings are 1/8" on the other side, so I should be able to just plug it right into the pressure/supply port. And thanks to your photo, I realize that the bushing in the kit was indeed a 3/8".

But, after long deliberation, I am going to have to have an "L" bracket fabricated so I can mount to the frame rail while, yet still clear the brake cable. There's always something...

I am about the pull the trigger on this. Is the picture below from this Kit? Do you know if the kit uses JIC for the hoses? I assume it is but it just says adapter on the parts list. I am currently running my aftermarket oil pressure gauge from the pressure port and figure I will just put in a T fitting to continue to monitor oil pressure. What is actually controlling the flow on this? Is there an orifice in the head? Thanks.

Update,

I was going to buy the whole kit til I looked closer and saw that I can buy just the amsoil filter head for 32 dollars. I have lots of 3/8 parker pushlok hose lying around and for less than 10 dollars in fittings and hardware I can get this thing going. The filter head is part number BK-303. Turns out it is the filter head that has the restricting orifice so the 3/8 hose wil be ok. Its so rad already having these ports. I just got to find out what size the lower one is. I know the upper is a 1/8 npt. By the looks of the picture it is probably a 1/4npt.

Update - upper pressure fitting is infact 1/8 npt and the bottom port is 3/8 npt. Hope this helps. here is a link for the fitting sizes. SpringerPop's Lube Bypass Filter

One option you have when mounting a bypass oil filter on a 4X2 Superduty or “X” is to mount the filter head inside the frame rail directly across from the full flow filter with a piece of angle iron. I have tried to attach a couple of pics of installs I have done before with both the Baldwin B164 and the Oilguard EPS-20 units. I hope this helps out.

From earlier thread:
I just installed an Amsoil single filter bypass after researching this and other sites. If you take the time to find it there is a post that identifies exactly which ports to use (THAT ALREADY EXIST) near the stock full flow filter. For less than 200 you get everything you need except the actual adapter to mount the filter base. By-Pass Filters and Mounting Systems, get the BMK-21EA. I got the big filter, and 7 foot of extra hose.
I bought an 8" long piece of aluminum angle, 1/4" thick and mounted it to the driver's right rear seat mount bolt and the other welded in nut next to it. This puts the filter just behind your transfer case, on a 4x4, and allowed me to use the biggest filter they had. The filter mount they send you bolted right to the angle aluminum really nice and secure.
The other end is even easier. You remove two plugs and use the fittings in the kit to mount the supply and return no problem. The stock filter is never touched.
I highly recommend this method, whichever filter company you go with.
Also, please note, there is a small hole in the filter mount that minimizes the amount of flow so you don't lose pressure.

BIG UPDATE:

OK, install was simple...but frustrating. Mainly because the 3/8" plug had that female square plug on it that is 5/16" square...and NO ONE seemed to even know what a keystock bar was (meaning HD, Lowes, Sears, etc.). I finally got one at an O'Reilly Auto Parts place, but it took them 20 minutes to realize I was wanting a "Straight Key." Ironically, the part number was "Straight Key / Keystock"...so I wasn't crazy. Wasted 3 hours trying to find it. I actually had an out-of-body experience during my search, in which I was transported back in time to when the Ford engineers decided on putting that unique plug on the truck...they were laughing and saying to each other, "We are going to screw with so many people by doing this! Ha ha ha ha ha!"

Also, on my 2000 Ex, that return hole was bigger than anything that came in the Amsoil kit. I had to buy a 3/8 to 1/8 brass bushing too...but it was only $4.

Overall, once you have a bracket made and a way to remove that female square plug...the install is very straighforward.

Good deal… I’m glad you were able to get the install done. I remember when I was looking for key stock the only folks that didn’t give me the “Deer in the headlight look” when I asked for it were the people at ACE Hardware or Orchard Supply House (OSH).
