I need a 2 quart filter with 3/4-16 Ford threads?

[SecondMonkey]

I'm trying to add an inline filter to my transmission, and while I'm at it, I want to increase the fluid capacity. Therefore, I'm trying to find a large, ~2 quart filter with 3/4-16 Ford threads. I need this type because I already have an oil filter adapter that size.

Does anybody know of such an animal? I looked up the numbers from all the Purolators in a big box I could find, but they all have 1.5" threads.

Amsoil makes a real good filter I am not sure on the number 'I would guess it is a 99# filter I am sure Gary Allen an Amsoil site sponser will let us know for sure .

Exactly what I needed! Thanks!

Remember...all the 2QT. filters listed are usually 24-30 micron, where as your standard 1Qrt Fl-1A typ. is 19-20 micro[finer filtration] if that mattrers to you. Most of the posters on this site opt. for the finer filtration, unless they really need more oil volume, then they add another filter or an oil cooler. I couldl be wrong but most auto manufacturers [SAE] specify 20 micron min. filtration

Or the original, Motorcraft FL-299. Don't know if it holds 2 quarts or not, but it's a big 'un!!

True. All the big boys are usually lower in nominal performance. It's a rough view though .. in my speculative "wonder if" way. I've argued this with Dave (dnewton3) a bit.

Disclaimer: This is 100% speculation in "back constructing" based on data available. It's mixed in with the crippling affliction of needing a rationale to support unknowns. That is, I can't just leave it as an unknown ..I have to try and come up with a reason. I mean, I spell out how I get there ..but it's not necessarily "true" due to lack of bona fide data.

FWIW

Look at THESE 3 filters. They're all 3/4-16 filters used on various Ford products (and others). Let's for the moment (just the moment) assume that they all use the same media and that the media area falls in some proportion to the can size (which Wix generally does - no "fooling you" with a big can and no content)

51348, 51516, and 51515. So we're going from small diameter/short length to small diameter/longer length, to larger diameter/longer length. Note how the filtering performance increases, but there's a diminishing rate of return for the added area.

Note that they don't have multi-pass data on the 51773 listed (not sure why .or rather why not) but the way the nominal (single pass test) is done, the 30um rating may just be due to the flow rate of the test and the massive (relatively) size of the media.

My speculation is ..that at a certain point of a fixed testing protocol ..that a massively bigger filter could invert the increased performance with going up in size (with a diminishing rate of return) ..to a loss in "apparent performance".

 

[Steve S]

I would guess the Amsoil would have the trick media.

 

[Gary Allan]

It has the same rating as the other EaO's. Beta15=75

 

[SecondMonkey]

Hmmm....so Purolator, for example, doesn't use the same filter media inside the big filter as they do the smaller ones? I'd like the Amsoil filter but I don't want to spend the big bucks plus shipping right now.

Which do you think would be better for an automatic transmission? The stock "filter" is just a screen. Would it be better to have more capacity and less filtration or the other way around?

I could use the Purolator PL3001, which is the same as my oil filter...but it's only about 1 quart.

If it's a Ford C6, you don't want to restrict the flow!! Trust me..

 

[Gary Allan]

Just use as big a filter as you can fit ..and make sure it has a bypass valve.

 

[Steve S]

that is the trick media.

 

[bmwtechguy]

If you already have the PL3001, then by all means use it. It will work fine. Remember you are filtering ATF which is not terribly viscous. To see how much if any flow you are losing by putting an inline filter in, just do a simple flow/time test to measure the quantity of oil that flows through the cooler line with, then without the filter in place. If it is within, say 90% of the flow without the filter (fluids at same temp both tests), then you are probably ok. It might be slightly more meaningful if you could also test this at lower ambient temps, when your ATF is a bit thicker, to see if it still flows through the filter ok.

Oil quart approx 60 cubic inches (up to oil level 2.25 x 4.25 x 6.25").

FL1A (Puro L30001): 5 x 3.5" is approx 48 cubic inches can volume.

FL299 (Puro L40017): 6.5 x 3.5 is approx 62 cubic inches.

Tractor flter (fits my FL1A application (Puro L30022): 5 x 4.25" is approx 80 cubic inches. I don't know what this is meant for, but when I picked it up (special order, next day) at Adv Auto, they guy said "Oh yeah, the tractor filter." I ended up wasting it because it made me have start up knock, either the antidrainback valve was not working or I finally found a filter that was too big.

 

[Saab9-3]

I am running a Eao26 filter on my saab. It allowed me to add 2 liters to the sump. See my write up regarding it.

Question: what filters better, the Ea or the donaldson?

 

[TallPaul]

I just picked up a 2 quart (1.89L) bottle of grape juice. It is
4.5 inch diameter by 7.5 to 8 inches long (shortening to account for the narrowing at the top).

So what is the length and diameter of this EA026 filter?

 

[Saab9-3]

The eao26 is the same filter size as the 51773 by wix.

6.998x3.663. It's huge. If you look for my write up I have many pics of the filters for comparison

 

[TallPaul]

The 51773 cross references to FL299 and that holds about 1 quart. You must have some other feature that is allowing your sump to increase by 2 liters. Maybe your filter is remote mount and the hoses add the remaining amount.

 

[Saab9-3]

nope. Nothng fancy, was able to put about 1.75liters into the filter to pre fill itand then added the remainder of oil. It is very slightly over filed but nothingt worry about.
