Backseat Bypass

[JaredH]

Situation:

So my BMK-21 Amsoil Bypass Filter has been lying in the backseat for a few months now. I want to mount the filter in a somewhat hidden location so it doesn't become the focus of attention upon hood opening. I would also prefer to not have miles of oil hose snaking it's way around the engine compartment. I want a clean install while keeping the hose length to a minimum. Here are my thought's: I just need some valuable views, info, thoughts, and experiences shared with me before I try the install (that may or may not work out so well).



Background:

I have already installed the GDP filter canister eliminator plate (with AD150 install). I have already drawn up an adapter plate (yes, a little more extensive than what is shown on my pic below, lol) which will bolt onto/around the GDP eliminator plate. The adapter will hold the Amsoil Bypass Filter housing. Not concerned with oil return, I will use "aux" freeze plug on pass side or valve cover return.



Question:

Oil Supply - Where to tap into oil supply? I know the norm is at the factory filter housing top. I am Looking for a supply on the driver's side of the engine this falls into my current scheme.



Option A. ) "T" off of the Oil Press. Switch as shown in the possibly generic Amsoil Install instructions (http://www.amsoil.com/bypassfilters/instructions/BP082.pdf). Who has tried this? I am concerned about pulling pressure/flow (however small) off of the main oil rifle, causing failure/excessive wear due to oil starvation or Engine Codes. I have read on TDR that there is literature from Cummins recommending a bypass filter orifice size of 2mm, any confirmations on that? Also, is there really any difference between pulling oil pressure/flow from the filter housing top or from the main oil rifle on the driver's side?



Option B. ) Ports in the driver's side of the block - The following is from a post on oil pressure sending units,

"there are 2 M10x1. 0 orb plugs that can be used [one above the ecm, one behind the cp3] and 2 M14x1. 5 ports. One M14 port is used by the stock switch, the other is inaccessible due to the fuel filter mounting bracket. "

(https://www.turbodieselregister.com...-oil-pressure-sender-dead-how-much-where.html) Is the fuel filter mounting bracket this person speaks of the same as the "mysterious plate" in my pic? Who knows which fittings will work the best, seems some people are having some difficult times getting them to not seep oil.



Option C. ) Give up on the driver's side... Mount the Bypass on the Pass Side Frame rail. I saw a PacBrake filter mount bracket that might work nicely (http://www.pacbrake.com/PDF/L5637.PDF). Know of anyone who sells the parts to these kits separately?



If anyone has any info please share! I want to get this install DONE.

If you are looking for a place to mount which will be somewhat hidden than you will not like my location. I fabricated a stainless steel bracket and bolted it next to my intake. I removed the factory sender, installed a T and ran the feed from there. I haven't had any oil pressure or any leaking issues since the install. I did use the heavy duty pink teflon tape on all fittings. I originally used a liquid thread sealer and every single brass fitting leaked oil. Replaced it with teflon and haven't had a leak since. The leaky issues that you speak of are probably do to improper installation and/or sealing of the fittings. Be very careful with the brass fittings as they are soft and break very easily. Good Luck.



Packbrake kit is really nice if your willing to spring for the $220.
