Remote filter housing for 95% system

There have been a couple of threads on bypass filters, housings, etc, that have me completely confused. I'm getting ready to get the filter housing for my 8CM engine with the 95% filtration mod. Looking for remotes, there are bypass adapters, bypass filters, remotes with filter bypass, without filter bypass, etc. Other than getting a filter with anti-drain back valve, I'm lost about the remote housing. Do I need a housing with a filter bypass in it? The ones I find open at 25 psi. It looks like it would let a lot of unfiltered oil through. It seems that they are for hydraulic applications, but I read that spin on filter applications on modern engines have a bypass built in. Can someone send me in the right direction for a housing for my application? Right now I'm thinking of a frame mount because of (1) being out of the way, and (2) with the housing lower than the engine, the lines won't drain back into the engine and have to be refilled on startup.
 
I used the filter housing from a late seventies GM v6 engine,so it had the bypass valve in it already
I made an alloy plate to mount it on .
the only thing I did not like was the filter itself was a bit small,but you could easy get a bigger one to fit.

There was a thread on this topic recently, believe the suggested filter was the more common Ford filters. It does have a by-pass for startup and plugged filter conditions, the by-pass is built into the filter. I also think almost any of the 3/4 spin-on filters have the correct by-pass function.

This and a fram ph8a and the plumbing is all you are going to need .Stop reinventing the wheel with the bypass anti drain all is inside the ph8a

Thanks Ronnie. Do the PH8A crosses (Wix, purolator, etc) all have the bypass and anti drainback?

Yes they all have same internals. They must as they are all for a ford and much more.

wix 51515
Hast lf115
Fram ph8a
Baldwin b2
Puro L30001
Fleetguard lf3313

Go to your auto parts store and buy your favorite flavor they all have a cross reference in the computer.

There u go for a start

The PH8a was a very common filter in the 60s, it was the filter used on a lot of military vehicles in addition to almost every Ford
 
I use the PH8 Fram on all my engines. There are several adapters with the outputs in several locations from side to top and one at ant an angle, so routing the lines should be very easy. I use3/8 PS return line. Now I lost ann engine last year due to the "stupid factor". I got the lines reverest and the check valve prevented oil flow for a short 6 mile run and the bearings didn't like that. pobodys nerfict.
 
On my engines as well as all the engines I build for others with the 95% system I only use Motorcraft FL-1A filters. I have found a delay in pressure readings on the oil gage when I use Fram / Puralator and other replacement filters.
With the Motorcraft FL-1A filter the pressure reading shows no delay. If you do a visual comparison of the perimeter holes in the base of each filter you will find the Motorcraft filter has long oval openings. The Fram /Puralator and others all have various amounts and sizes of small round holes with a surface area that's less than the Motorcraft design. Go to Wallmart and see for yourself compare brands they are not all created equal.
 
Ronnie, I too found that ,what I think happens is the oil drains back ,as my filter is above the oil level, If I used a fleet guard or other brand filter, the one that did not was the Repco one,.
I think it had a better anti drain back flap thing in it.
I don't know if we have access to the motocraft one,will go to the ford dealer and check, mind you,these are the guys who wanted to know what sort of car I was in when I went there in the 33.

The Ford-type filters (Fram PH8A, motorcraft FL1A, etc) show to have filter bypass relief valves that open at 11-14 psi. Isn't more oil bypassing the filter than is going through it? The stock by-pass system is looking more legitimate all the time.

If this were true (absolute pressure not differential) how would these filters work on modern high performance engines? They wouldn't, so obviously that is not how they work. This is one of the most common filters used for many years. Don't make a simple filter selection so complicated.
 
The best filters are Wix or at least they were last time I checked. Of all the different brands I've cut apart over the years, they have the best paper element of the automotive brands. All the others can be torn apart easily. The Wix paper is as strong as the stuff used in aircraft filters like Champion Aerospace products.

Most filters have a spring and a rubber valve in them for bypass in case the paper gets clogged. Looking at that filter test sheet data, I'd say that there is a lot of misinformation there. If you cut the filter element out of the can and look for yourself, you will see what I mean. I don't trust folks enough to believe half of what I read now days.

Yup x2

All the filters sold only have to meet the minimum OE requirements.
Some exceed the standard. Most only meet the min as it is easy to reach.
In a graduating class of doctors 50% are in the bottom of the class "LOL"
You need to do an SAE filter test to determine the outcome.
